| // As usual the algorithm get more complicated than I originally |
| // envisioned. I believe that this is as simple as it is possible |
| // to do it with the features I want. It's a good exercise to start |
| // thinking on how to do this to convince your self that all this |
| // is really needed for the general case. |
| // |
| // The algorithm two draw 3D pies without "real 3D" is done in |
| // two steps. |
| // First imagine the pie cut in half through a thought line between |
| // 12'a clock and 6'a clock. It now easy to imagine that we can plot |
| // the individual slices for each half by starting with the topmost |
| // pie slice and continue down to 6'a clock. |
| // |
| // In the algortithm this is done in three principal steps |
| // Step 1. Do the knife cut to ensure by splitting slices that extends |
| // over the cut line. This is done by splitting the original slices into |
| // upto 3 subslices. |
| // Step 2. Find the top slice for each half |
| // Step 3. Draw the slices from top to bottom |
| // |
| // The thing that slightly complicates this scheme with all the |
| // angle comparisons below is that we can have an arbitrary start |
| // angle so we must take into account the different equivalence classes. |
| // For the same reason we must walk through the angle array in a |
| // modulo fashion. |
| // |
| // Limitations of algorithm: |
| // * A small exploded slice which crosses the 270 degree point |
| // will get slightly nagged close to the center due to the fact that |
| // we print the slices in Z-order and that the slice left part |
| // get printed first and might get slightly nagged by a larger |
| // slice on the right side just before the right part of the small |
| // slice. Not a major problem though. |

| 30 May 2003 JpGraph 1.12.2 |
| ========================== |
| * [me & A. Tang] Added support for Chinese font and character handling. |
| This requires you to install the "simhei.ttf" Chinese font. |
| * [J Sweat] Fix bug [#124] Make step line style ignore NULL values in data |
| * [J Sweat] Fix bug [#123] Divide by zero for line length of zero for dashed lines |
| * [me] Fix bug [#109]. Problem with pie color when a supplied color array |
| contains more colors than data. For anti-aliased images that meant that |
| the last n colors was used and not the first n colors. |
| * [me] For plotmarks that use the ALT string the wrong value was in due |
| to the recent addition of both Y and X value to control the plot callback. |
| This has now been fixed so that it will work as before and that previous |
| code that assumes one parameter in their ALT srting will see the Y-value at |
| the plotmar. New is also that the X-value is given as a second |
| parameter. This means that the ALT string can display both the Y and X value |
| for a specific point. |
| * [me] Make it possible to disable individual plot legends through the method |
| Plot::HideLegend() |
| * [me] Fixed problem with SetTextTickInterval() together with grouped bars |
| (bug #116) |
| * [me] Fixed a problem with shadows on accumulated bar plots (bug #111) |
| * [me] Fixed Legend::SetMarkAbsSize() |
| * [me] Add error check for the case that the server (Windows) |
| doesn't support SystemRoot and TEMP server variables. |
| * [me] Fix short-open-tags bug that made it's way into 1.12.1 (bug #121) |
| * [me] Make sure we only pass integers into GD when positioning texts. |
| * [me] Always treat "" (empty string) as NULL for bar plots |
| * [me] Allow links from vertical position 0 on gantt charts |
| 12 Apr 2003 JpGraph 1.12.1 |
| ========================== |
| * [me] Added Legend::SetLineSpacing() to control the vertical line |
| distcance (in pixels) between legend texts. |
| * [me] Compensate for bug in imagecopyresampled() in GD 2.01. |
| This made clipping unusable with GD 2.01 |
| * [me] Added LinePlot::SetFillFromYMin() to make the fill start from |
| the bottom of a Y-scale with negative values rather than the 0-value |
| which is now the case. |
| * [me] Fix a problem with legend box layout in the case of TTF fonts |
| and different lengths of individual texts. The layout engine now |
| work out each column individually. This will also give the legend |
| box the minimum possible size. |
| * [me] Compensate for possible bug in strtok() when parsing color |
| specification as a string with adjustment factors. |
| 06 Apr 2003 JpGraph 1.12 |
| ======================== |
| * [me] Added possibility to specify the position of the legend box |
| with absolute pixels coordinates not only as fractinos as before. |
| * [me] Improved legend layout. It is now possible to specify |
| the number of columns in the legend box. The preferred way of |
| specifyin the layout is now Legend::SetColumns(). The oild |
| way with SetLayout() is still available for backwards compatibility |
| reasons. The old vertical layout corresponds to a 1 column |
| layout (SetColumns(1) which is also the default). |
| * [me] Added possibility to specify text string position |
| using scale coordinates onto the plot by adding |
| Text::SetScalePos(). The autoscaling has been modifyied to |
| be aware of the text scale positions. |
| * [me] Added builtin images for plotmarks. This also meant a |
| refactoring exercise for the PlotMark class and it has now been |
| split in sevaral files. |
| * [me] Added footer capability to Radar, Pie and Gantt charts |
| * [me] Improved upon rounding problem with GD2 and pie slices |
| (defect #88) |
| * [me] Take shadow color as specified with Graph::SetShadow() into account. |
| * [me] Don't rotate the footer if the graph is rotated. |
| * [me] Added Axis::HideLabels() |
| * [me] Adjusted of the automatic margin calculation so that it is |
| aware of when the x-axis have been hidden. |
| * [me] Added PlotMark::SetCallbackYX(), This allows for the |
| specification of a callback function which is given both X and Y |
| coordinates. Also extended the returned values from the callback so |
| that image in a marker can be dynamically modified both size and |
| actual image file used. This will enable the use of advanced |
| "push-pin" graphs. For example adding markers to a background image |
| map of certain size and type. |
| For backwards compatibility any callback specified with |
| PlotMark::SetCallback() will not be given the extra parameter. So |
| old code does not need to be changed. |
| * [me] Fixed handling of PHP array URL parameters with CSIM. [Bug #82] |
| * [me] Added Legend::SetFrameWeight() which adjusts the frame around |
| the legend. Legend::SetLineWeight() now works as documented and sets |
| the line weight for the markers instead. |
| * [me] Autoscaling will now also take the value of added lines into account. |
| * [me] Fixed problem with horizontal legend box becomming too small |
| for many legends. |
| * [me] Radar plot. SetColor() always sets a fill color. Fixed (Bug #83) |
| * [me] Added SetWidth() for tab-title. The tab can now easily extend |
| over the entire plot width. Added SetPos() as synonym in tab title |
| for SetTabAlign(). |
| * [me] Gradient bar plots now show a gradient mark in the legend |
| * [me] PiePlot3D::SetSliceColors() now more correctly specifies the |
| color anti-clockwise. The same order that slices are drawn. |
| * [me] Pie position can now also be specified in absolute pixels |
| in PiePlot::SetCenter() |
| * [me] Added Bevel frame for entire graph |
| * [me] Added possibility for some more advanced Graph title |
| formatting through the Graph::SetTitleBackground() method. |
| * [me] Type safe comparison in auto-detection of GD version |
| * [me] Added Graph::SetCanvasColor() to specify the background color |
| the canvas is initialized with. |
| * [me] Fine tuned label positiong for pie labels and made 3D pies |
| take the specified labels into account. |
| * [me] Added Anti-aliasing to Pie charts. Looks good but it really |
| slows down the pie generation. Enable by acalling |
| PieGraph::SetAntiAliasing() |
| * [me] Ignore NULL values in Stock and bar plots |
| * [me] Some minor internal adjustments for rounding in log scales. |
| 2 Feb 2003 JpGraph 1.11 |
| ======================= |
| * [Martijn] Compensate for GD 2.x bug in filledarc() which doesn't |
| like negative angles. |
| * [me] Added Graph::SetBackgroundGradient() . This allows |
| a gradient to be used as a background. The gradient can either fill |
| the whole frame, only the margin or just the plot area. See the |
| class reference or the manual for details regarding this method. |
| * [me] Modified adjustment factor for colors so that it now |
| is linear between dark and light, i.e. a factor of 1 is the original |
| color, a factor of 0 is black and a factor of 2 is white. |
| * [me] Added two new gradient style GRAD_LEFT_REFLECTION and |
| GRAD_RIGHT_REFLECTION |
| * [me] Some fine tuning of text layout in legend box |
| * [me] Radar plots can now have a background image and multiple |
| titles (sub-title, and subsub title). |
| Added RadarGraph::SetPos() as alias for |
| RadarGraph::SetCenter(). |
| * [me] Fixed a small pre-read-loop error which could casue the |
| X-gridline to be outside the right edge of the plotarea if the |
| X-scale was indented. |
| * [me] Added possibility to use (scaled) images as markers by |
| introductin the new mark type MARK_IMG. |
| * [me] Added tab titles for graphs. See class reference and Example |
| tabtitleex1.php. |
| * [me] Added filled grids by adding method Grid::SetFill(). This new |
| feature is illustrated in example filledgridex1.php. Documented in |
| section 6.2.11 in the manual. |
| * [me] Improved automatic margins so they adapt to one or more title |
| lines automatically. |
| * [me] Fixed a class hierachy bug. RotImage::DashedLine() should not be |
| implemented but rather rely on the Image::DashedLine() since the |
| rotation will happen in the RotImage::Line() which gets called in |
| Image::DashedLine() by any istance of RotImage(). |
| You could see the ffect of this by trying to create a 90 degrees |
| rotated graph with dashed gridlines, they would appear not to be |
| rotated at all where in fact they were rotated twice. |
| * [me] Added automatic default margins when using Set90AndMargin() |
| * [me] Added Box plots which is a variant of Stock charts with the |
| possibility to add the median as a horizontal line in the box. |
| * [me] Added Stock charts, (aka candle-bars) as new class StockPlot(). |
| added example stockplotex1.php in the Example directory. |
| * [me] Added two new axis styles AXSTYLE_YBOXOUT, AXSTYLE_BOXIN which |
| suplicates the Y-axis on both sides but not the X-axis. |
| * [me] Set90AndMargin() now also adjusts the label alignment on the |
| axis to suit the rotation. |
| * [me] Added class LineErrorPlot which alolows a line plot to |
| have error bars (+/- delta error). |
| * [me] Added Ticks::SetSize() |
| * [me] Modified size for plot mark circle so it will have the |
| specified width as radius and not as diameter. |
| * [me] Added Ticks::SetSize() to be able to set the absolute size |
| in pixels of the tick marks. |
| * [me] Default directories for Fonts and Cache now gets set |
| automatically. |
| 13-Jan 2003 JpGraph 1.10.1 |
| ========================== |
| * [me] Fix bug in Band pattern Left diagonal and Right Diagonal where |
| the drawing was incorrect when width < height |
| * [me] Take the border on/off switch into account for line AddArea() |
| * [me] Added color parameter to Axis::SetTickLabels() to make it |
| possible to set individual colors on labels. |
| * [me] Fixed PiePlot::SetSliceColor() so that colors are now specified |
| in the same order as slices. |
| * [me] Gantt, Radar and Canvas graph now also considers the special file |
| _IMG_HANDLER (returns the actual image handler and doesn't stream |
| picture back) |
| * [Christian Reiser] Pie graphs can now also return the IMG_HANDLER |
| * [Richard Black] Removed case sensitivity for extension of |
| background images. Added support for handling file names with |
| multiple '.' characters in the path for background images. |
| * [me] Added error check for imagettfbbox() since it can give |
| a file not found error even though both file_exists() and |
| is_readable() reports that the file exists and is readable |
| in the case when PHP basedir restriction is in place. |
| * [me] Corrected CSIM handling in Gantt for non-file based |
| Gantt charts. |
| * [me] Note to self: 1.10p |
| * [me] Gracefully handle the abnormal case where no valid data points |
| is included in the Y-data array when creating a line plot. |
| 16-Dec 2002 JpGraph 1.10 |
| ======================== |
| * [me] Added GanttGraph::CreateSimple() whihc is a utility method to |
| help create simple gantt charts with a minimum of code. |
| * [me] Added new plot (FieldPlot) type which handles field plots. This is |
| basically a variant of scatter plots where each point is represented |
| as an arrow which a specific direction (0-360 degrees). |
| * [me] Added Graph::SetY2OrderBack() to control of plots on Y2 should |
| be under (in z-order) te plots on Y. By default they are on top. |
| * [me] Avoided a potential 1-pixel off rounding problem if a user |
| supplies a non integer canvas width and height in the Graph() call. |
| * [me] Added two new formats for week scale in Gantt |
| charts. WEEKSTYLE_FIRSTDAYWNBR, WEEKSTYLE_FIRSTDAY2WNBR These |
| formats adds the weeknumber as well to displaying the date of the |
| start of the week. Also tweaked the auto-sizing of the Gantt charts |
| to adjust for the size of the text in the week scale. |
| * [me] Fixed wrong define in jpgraph_gantt.php for WEEKSTYLE_DAY2 |
| (Bug #45) |
| * [me] Improvements on manual scaling. If a manual scale is specifed |
| (in the Graph::SetScale()) you are now longer required to specify a |
| major and minior tick interval (but of course you can still do it |
| with a call to Ticks::Set() ). |
| A suitable intervall will be automatically |
| caclulated in the same way as for autoscaling. By default the exact |
| limits for the scale as specified will be used. This means that |
| depending on the scale and tick intervall chosen the max value of |
| the scale may or may not fall on a major tick mark. If you want that |
| behaviour you need to call Scale::SetAutoTicks(). By using this call |
| you give the algorithm permission to slightly adjust the specified |
| min and max values (if needed) so that they wil fall on a even |
| major step. |
| * [me] Added error check if user tries to use SetTextLabelStart() |
| with a logarithmic scale (where it is undefined). |
| * [me] Default marker for scatter plots are now a filled square |
| * [me] Adjusted the x-axis labelling for a 1-pixel off limit. Which |
| sometimes (depending on the image size and scale) could cause a |
| linear scale's last label not to be shown. |
| * [me] Fixed bug report #40 |
| * [me] Fixed positioning of caption for full odometers. (Bug #34) |
| * [me] Fixed spelling mistake in jpgraph_odo.php which casued |
| Odometer::SetLabelPos() to have no affect. (Bug #33) |
| * [me] Fixed an overzeoulous optimization which skipped both rotation |
| and translation for angle=0. Addresses (Bug #36) |
| * [me] Colors can now include an alpha channel specification as well. |
| The alpha channel is specified in the text string separated by a |
| a '@' , for example "red@0.5". The alphachannel is specified as a |
| fraction between 0.0 and 1.0. |
| * [me] Improved filled line plots so they now handle negative values |
| in a more standard way. |
| * [me] Added automatic detection of what version of GD is installed. |
| * [me] Aligned the order of legends and slices for pie and 3D pies so |
| that they now follow the more common order of clockwise slices with |
| legends from top to bottom. |
| * [me] Changed call to deprecated function SetLinePos() to SetLineSide() |
| * [me] Added clipping to generated plots. This means that if you have |
| plots (for example lines) which extends outside the scale range it |
| will be clipped. This might come in handy in for example balloon |
| plots. Clipping is enabled by default but can be controlled by a |
| call to Graph::SetClipping() |
| * [me] Fixed a problem with circles and filled circles when they were |
| rotated twice in a rotated graph. (Bugtraq #26) |
| * [me] Added Graph::Set90AndMargin() which helps for doing a 90 |
| degrees rotation and getting the margins right. (Otherwise you have |
| to adjust them manually since height becomes width and width becomes |
| height when you rotate 90 degrees) |
| Changed the horizbar* examples to use the Set90AndMargin() |
| * [me] Changed the behaviour of plot marks in legends. The possible |
| format callback is no longer called. Instead the plotmarks are |
| set to a default size. |
| * [me] Added three more plotmarks MARK_LEFTTRIANGLE, |
| MARK_RIGHTTRIANGLE, MARK_FLASH. These new types are primarily meant |
| to be used with GanttCharts. |
| * [me] Added constrain lines to GanttCharts. It is now possible to |
| illustrate start-end, start-start, end-start and end-end |
| constrains. This is illustrated by adding lines with arrows, |
| Use GanttPlotObject::SetConstrain() |
| * [me] Added Image map support for Gantt chart. Bar and titles can now |
| have associated image map targets. Use GanttBar::SetCSIMTarget() |
| GanttBar::SetCSIMAlt() and for titles use |
| GanttBar::title::SetCSIMTarget() and GanttBar::title::SetCSIMAlt() |
| * [me] Fix problem in Gantt graph whereby the progress bar indicator |
| could extend over the end date if an explicit date scale was set. |
| * [me] By default logarithmic scale now print the labels as 10^3 |
| instead of 1000. You can change the behaviour with the new |
| method for logarithmic ticks, SetLabelLogType(). |
| Also added the possibility to have a callback for log scales |
| * NOTE TO SELF 1.9p |
| * [me] Added the possibility to specify a value > 1 as the position |
| for labels in PieGraph::SetLabel() to increase the margin between |
| the label and the edge of the pie. |
| * [Olaf Kandel] Fixed subtle bug in the printing of the month scale for the |
| case where the start and end month hjave the same number but |
| are on different year. This would cause the width for the |
| first month to be wrong. |
| Jpgraph 1.9.1 |
| ============= |
| * [me] Fixed defects #20 and #21 (spelling mistake and and one |
| overzelous last minute error check I added). I have to eat a lot |
| of humble pie over these ones. Sorry to all who have been affected. |
| What can I say? Human error........ |
| JpGraph 1.9 |
| =========== |
| * [me] Changed the way TTF fonts are handled. The font files are no |
| longer distributed with JpGraph due to potential copyright problem. |
| This change also has the advantage that it is now very |
| straigthforward to install new fonts whatever their naming |
| conventions are. |
| 1. If you are running on a standard Windows system just point the |
| TTF directory to your standard font directory and use the available |
| fonts in windows. |
| 2. If you are on a Unix system you can download the MS Core TTF |
| files from http://corefonts.sourceforge.net/. The old MS EULA allows |
| distribution of the fonts in unaltered form (Win EXE) and this |
| project exercises this right and provide tools to download and |
| install the fonts on a UNIX system. |
| * [me] Renamed this release from 1.8.1 to 1.9 due to the big |
| change in the handling of TTF fonts which breaks backward |
| compatibility due to the copyright problem with TTF fonts. |
| * [me] Improved the TTF pargagraph layout engine for consistency |
| in handling "\n\r" vs "\n". It is now always sufficient to |
| use just "\n". |
| * [me] Adjusted the text positioning for StrokeBoxedText() |
| to use the new GetBBoxHeigh() and GetBBoxWidth(). |
| * [me] Added Image::GetBBoxHeight(), Image::getBBoxWidth() |
| * [me] Once and for all fixed the handling of rotated TTF text by |
| adding Image::GetBBoxTTF() which returns the bounding rectangle |
| (which is not the same as the bounding box except for angle==0) |
| * [me] Added argument to Legend::SetColor() to make it possible |
| to specify both frame and font color. |
| * [me] Cosmetic adjustment of markers in legend so that they are |
| positioned exactly in the middle of the text string. |
| * [me] Corrected the positioning of TTF fonts when defining the |
| hotspot as 'bottom'. It could be up to 4 pixel off when using |
| texts that contained character that extended below the TTF |
| baseline e.g. '('. |
| * [me] Added possibility to use a cache system with CSIM images |
| as well. The cache system is used slightly, slightly different |
| and require a call to the new method Graph::CheckCSIMCache() |
| This is unfortunately unavoidable due to the nature of CSIM in |
| HTML. The documentation is updated to deal with this. This also |
| added two more defines CSIMCACHE_DIR and CSIMCACHE_HTTP_DIR |
| * [me] Added CSIM (Client Side Image Maps) to legends, added |
| target and alt arguments to all Plot::SetLegend() |
| * [me] Added functionlity to pass on any URL arguments when using |
| StrokeCSIM() (Bug: #006) |
| * [me] Fixed so that Gantt charts can again have just the width |
| specified and have the height automtically sized. (This was a |
| regression introduced in 1.8) (Bug #005) |
| * [me] Added error check for return value from imaagecolorsforindex() |
| in Anti-aliased lines. In combination with GD2, no-true-color, a |
| true color background (ala JPG) this can fail since it gets a color |
| which doesn't exist (since it uses imagecolorat()). |
| * [me] Improved edges support in 3D Pies. |
| * [me] Changed Image::Polygon() so i now draws an open polygon and not |
| a closed one. |
| * [me] Legends for scatter plots no displays the mark used for |
| each scatter plot and not just a square with the correct |
| color. |
| * [me] Fixed a small cosmetic problem in that horizontal legend |
| box was sometimes not wide enough and made a small adjustment |
| of the positioning of marks in the legend box for better |
| apperance. (Bug #0017) |
| * [me] Improved manual by adding linked TOC. |
| * [me] Added Bezier curve to canvas Shape class. Added Bezier canvas |
| example canvasbezierex1.php |
| * [me] Added Paragraph Alignment setting in Text::Align() as well to |
| avoid seprate call to Text::SetParagraphAlign() |
| * [me] Added Image::SetExpired() . By default the image now sends |
| back a couple of variants of "no-cache" headers to force the browser |
| to reload. |
| * [me] Some serious speed improvments for 3D Pie plots. It can now be |
| up to 6000% faster (yes that's right 6000%!). This is the way I had |
| planned on doing it but for time reasons were pushed out of 1.8. |
| I have completely changed the algorithm that handles the individual |
| slices on the expense of a slightly more complicated implementation. |
| This means that there is no performance difference between 2D and |
| 3D Pie Plots. |
| * [me] Fix bug for rotation of paragraphs (multi-line) texts. |
| A limitation for now is that rotated pargraphs always gets |
| paragraphs align "left". (Bug: #008) |
| * NOTE TO SELF: 1.8p |
| * [me] Fixed a typo that had the strange affect that paragraph strings |
| which started with a number would have larger distance between the |
| individual lines since that number would be interpretated as the |
| angle for the text! |
| * [me] Fixed a problem with marks getting out of sync if NULL values |
| are present in the line plot. (Bug #0018) |
| * [me] Scatterplot no skips NULL values instead of treating them |
| as zero. |
| * [me] Added LinearScale::SetAutoMax() as complement to SetAutoMin() |
| * [me] Added LinearScale::SetAutoTicks() this makes it possible to |
| manually set a scale but still have the tick marks automatically |
| determined. By default this feature is off to keep old code |
| behave exactly the same as before. If this is enabled any |
| Ticks::Set() calls are ignored. |
| * [me] Added possibility to adjust the position of the displayed |
| value for bars via the BarPlot::SetValuePos() method. Added new |
| example example20.5 to demonstrate this. |
| * [me] Bugfix: Fixed color themes for 3D pie plot. The color array |
| was not wrapped around in the case where more slices (data points) |
| than colors is used. (Bug: #001) |
| * [me] Documentation is now 100% pure HTML and does not require |
| any PHP. Previously a PHP script was used to generate the |
| highlighted source used in the image/source frames. All this |
| is now pre-generated in the docs. |
| * [me] Position the values in a scatter plot in the center of the |
| plot mark by default (Setting align to 'center','center' and margin=0 |
| * [me] Added LinePlot::SetBarCenter to make it possible to center the |
| line on the bars when combining a plot with both bars and lines. |
| The new example 'ceneterdlinebarex1.php' demonstrates this. |
| [19-Sep-2002] JpGraph 1.8 |
| ========================= |
| * [me] Added Text::SetPos() as alias for Text::Pos() to harmonize with |
| other setting methods. |
| * [me] Made Graph::Add() polymorphic. You can now use Graph::Add() to |
| add all plot objects and you don't longer have to use AddText(), |
| AddLine(), AddBand() and so on. |
| * [me] Added PiePlot::SetLabelPos(), added some more Pie examples. |
| * [me] Improved the API for class Text by adding SetShadow() to make |
| it more like the other objects. Extended Text::SetBox() with shadow |
| width and corner radius. |
| * [me] Added the possibility for Text object to use the new rounded |
| rectangles as the filled background. |
| * [me] Added possibility to add arbitrary labels inside the pie plot |
| * [me] Added special filename __IMG_HANDLER to make it possible to |
| have Graph::Stroke() return the image handler instead of stroking |
| the image to file (or stream it back). |
| * [me] Improve FilledCircle() to avoid moire-patterns in circle. |
| * [me] Added middle type pie plot |
| * [me] User specified values for the band position is truncated to the |
| min and max values of the axis. |
| * [me] Added possibility to use Text::SetMargin() for all the titles |
| in a graph |
| * [me] Added SetSize() as synonym for SetWidth() for plot marks. |
| * [me] Updated some of the examples with more comments. |
| * [me] Fixed problem with with jpg background images wrongly being |
| loaded with imagecreatefromjpg instad of imagecreatefromjpeg |
| * [me] Corrected the positioning of individual titles for 3D |
| plots. |
| * [me] Added Text::SetMargin() to make it easy to have context |
| sensitive margins. |
| * [me] Added capability to have background images on Pie and 3D |
| Pie plots |
| * [me] Added method Axis::HideLine() which hides the axis line but |
| nothing else. |
| * [me] Fixed bug in Stroke::Text() where negative coordinates |
| wasn't properly handled. We must allow negative absolute |
| coordinates since these might be rotated/translated into |
| "real" screen coordinates. This fixes the bug, for example |
| in bar_csimex1.php where the first value of the bar wasn't |
| displayed. |
| * [me] More adjustment of how the rounding takes place with |
| coordinates. This should now avoid all potential difference |
| between different graphic objects. |
| * [me] When you use automatic labelling on text scale it now starts |
| at 1 and not at 0. This makes more sense since most people (except |
| mathematicians) start counting from 1. |
| * [me] Example directory: |
| - Added more advanced canvas examples |
| - Updated all CSIM examples |
| - ~60 new example script which are used in the new documentation |
| * [me] Compensate for bug in imagettfbox() which return to small size for |
| large fonts. |
| * [me] Added jpgraph_canvtools.php which contain some utility classes for |
| use with canvas graphs. |
| * [me] DOCUMENTATION: The class reference is now included in the release. |
| * [me] DOCUMENTATION: Completely rewritten the original |
| Word-introduction to JpGraph to pure HTML. This will be a living |
| document that will be updated as time moves on. This is currently |
| considered "Beta" and more chapters need to be added but this is |
| a good start!! |
| * [me] Added full support for multiline legends. (See for example |
| nullvalueex01.php. Also improved the way lineplot with marks |
| are illustrated in the legend by adding the line underneth the |
| plotmark. |
| * [me] Added some utility classes to be able to draw DB schema for |
| DDDA. This is tailored for my DB abstraction layer (jpdb.php) |
| in DDDA but is generic enough to work in other circumstances as well. |
| The classes can be found in utils/misc/imgdbschema.inc |
| Please see (run) dbschema_ddda.php which shows how it looks |
| in a real life example. |
| * [me] Tweaked the positioning of TTF fonts and how the width and |
| height are determined. Making more carefull assumptions about |
| how the baseline is handled for individual lines of text. |
| * [me] Added class RectangleText() which makes it easier to work |
| with text inside a rectangle with rounded corner. |
| * [me] Added support for multi-line TTF paragraphs with paragraph |
| formatting. This was previously only supported for the builtin |
| fonts. All text object should now support fully formatted paragraphs |
| of text. |
| * [me] Added Image::RoundedRectangle() and |
| Image::FilledRoundedRectangle() |
| * [me] Added format callback to plot marks. This makes it |
| possible to individually adjust the plot marks depending |
| on it's specific data value. See balloonex1.php |
| * [me] Added some initial support for super script used for |
| scientific numbering, i.e properly print for example 10^2 |
| where the 2 is in superscript. This is all handled by the |
| new class SuperScriptText(). Not yet used in the actual |
| labels drawing but will be added shortly. |
| * [me] Added a small tool mkgrad.php in the utils directory to |
| make it a breeze to create gradient squares which may be |
| used as background images. |
| * [me] Added footer class to graph. This makes it easy to have |
| left,center and right footers in your graphs. |
| * [me] Added subsubtitle to graphs |
| * [me] Improved/Changed the way you work with CSIM. This new method |
| makes it possible to generate CSIM without having to create an |
| intermediate image on disk. |
| Added Graph::StrokeCSIM(). Added new chapter in the docs on how to |
| work with CSIM |
| * [me] Changed naming of Spider* to Radar* since SpiderGraph is a |
| copyrighted name. |
| * [me] Modified the automatic suppression of the first value of the |
| X-axis when the Y-axis have negative value so it don't happen |
| in the case where the X-axis is positioned at the minimum of |
| the Y-axis. |
| * [me] Fixed spelling error of BK* instead of the correct BG* |
| for the default settings of background image style. |
| * [me] Some internal code changes to RGB() class to make it easier |
| to use directly for external scripts. |
| * [me] Changed the behaviour of filled line plot so that they |
| don't go down to 0 for null values in the plot but instead |
| behaves like '-' for non-filed plots, just ignore them and |
| connect the previous and next point instead. |
| * [me] Fixed problem in integer scaling where it certain scale |
| combinations could generate floating point labels! Ooops.. |
| (Affects IntCalcTicks()) |
| [5-July-2002] JpGraph 1.7 |
| ========================== |
| * [me] Removed the APACHE_CACHE_DIRECTORY define since it is |
| not used. |
| * [me] Added Image map functionlity for rotated bar graphs, |
| also added new example for this (bar_csimex3.php) |
| * [me] Made Ticks::SetPrecision() deprecated. Use SetFormatString() |
| instead |
| * [me] Fixed problem with incorrect string being returned from |
| ToCyrillic() |
| * [me] Allow Y2 axis to use "int" scale |
| * [me] Fixed problem with wrongly names framework function for |
| patterns |
| * [me] Fixed small problems with margins being slightly off for |
| roated images. |
| * [me] Changed name of PlotMark::SetMarkColor() to PlotMark::SetColor() |
| for consistency |
| * [me] Added example with "hidden" Y-axis. |
| [17-June-2002] JpGraph 1.7-BETA |
| =============================== |
| * [me] Added DisplayValue::SetFormatCallback() to make it possible to use |
| a user specified formatting callback routine. |
| (Note:: Yes, this is very nono-OO but the proper OO way, by forcing the |
| user to define a subclass of the plot class where the formatting method |
| is overridden will probably not fly with to many non-OO PHP peoples since |
| a callback is conceptually simpler.) |
| * [me] Added DisplayValue::HideZero(). Makes it possible to hide zero values |
| in labels, for example zero slices in pie's, (e.g. $pieplot->value->HideZero()) |
| * [me] Added manual scaling to Gantt graphs, added example to illustrate |
| this, fixscale_gantt.php |
| * [me] Adding image maps for Y2 scale as well. |
| * [me] Fixed a small bug which made it impossible to use BRAND_TIMING with |
| Gantt charts. Enabling timestamping of graphs would give a "PlotArea to small" |
| error. |
| * [me] Made a very small change to the AutoScaling algorithm to yield tighter |
| boundaries, i.e with the existing algorithm, depending on rounding problems |
| a plot which had a maximum value of, say 4, could get a autoscaling max |
| value of 5. Not a big problem (or hardly a bug) but not what I wanted. |
| All my 111 test cases works fine with the modification but I'm still |
| not convinced that this (very minor) adjustment is 100% (I can distinctly |
| remember that I had a good reason to do it the original way, I just can't |
| remember what :-) |
| * [me] Graph titles may now have multiple rows. By default the lines will |
| be centered, but this may of course be adjusted by a call to, for |
| example, $graph->subtitle->ParagraphAlign('left'); |
| * [me] Added class FuncGenerator() to make it easy to generate |
| function plots (both normal and polar). To illustrate this I have |
| added three new examples funcex1.php,funcex2.php,funcex3.php. |
| * [me] Added Axis::HideFirstLastLabel() to hide first and last label on |
| axis. This is usefull if we have a box around the plot area and we don't |
| want the labels to owerwrite the box (see funcex1.php) |
| * [me] Make sure GD2 variables is registred in $GLOABALS[] |
| * [me] Fixed bug in image maps for marks. Alt strings was incorrectly |
| indexed so it was only using values 0,2,4.. instead of 0,1,2,... |
| * [me] Added Graph::SetAxisStyle(). This makes it easy to use |
| a few number of preset axis setup. For example duplicating the axis |
| as a border around the plot. Preset axis position availabel are |
| AXSTYLE_SIMPLE, AXSTYLE_BOXIN, AXSTYLE_BOXOUT |
| * [me] Made Axis::SetTickLabelMargin() deprecated. Use |
| Axis::SetLabelMargin() instead. Name change to make it more |
| consistent with the other margin settings. |
| * [me] Made Ticks::SetSide() a synonym for Ticks::SetDirection() |
| to make it consistent with side setting for labels and values. |
| * [me] Added Axis::HideZeroLabel() as a shortcut for |
| axis->scale->ticks->SupressZeroLabel() |
| * [me] Internal code changed. Replace the use of FontProp in SpiderGraph |
| with Text() and some additoinal code cleanup. |
| * [me] Adjusted Image::Arc() so that no negative angles are |
| passed on to GD imagearc() since it barfs at negative angles. |
| * [me] Added PiePlot3D::SetHeight() which is used to specify the |
| height in pixels of the 3D pies instead of using the default |
| height. |
| * [me] Pie plots (both 2D and 3D) now displays the slice labels |
| by default. |
| * [me] Added two more Examples. barintex1.php shows how to use |
| integer scale and barscalecallbackex1.php shows how to use |
| a callback function for formatting the scale. |
| * [me] Modified grace calculation for Integer scale to have higher |
| sensitivity. |
| * [me] Restructured code so class DateLocale is now in jpgraph.php |
| rather than in jpgraph_gantt.php. Also added $gDateLocale as a |
| global instance of the class DateLocale |
| * [me] Modified integer autoscale to correctly handle very small values |
| (needs special handling of max==1 to avoid fraction) |
| * [me] Changed the way min value is extracted when finding the baseline |
| for bar plots. Now uses the function Scale::GetMinVal() instead of |
| reading the value directly fomr the instance variable. This makes it |
| work better with logscales so that the bar starts from the min value |
| of the log scale. Also added check in bar PreStrokeAdjust() to see if |
| we are using a log Y-scale to automatically adjust the Y-base. |
| * [me] Optimized Stroke() loop for LinePlot so calls to PlotMark::Stroke() |
| will only be done if the marks are really to be shown. |
| * [me] Added Axis::SetLabelAlign(). |
| * [me] Made some internal modifiaction on how Axis title gets aligned |
| to make it possible to specify it manually without having it |
| automtically set. This makes it possible to generate nice |
| horizontal bar graphs. |
| * [me] Added three examples in the Example directory on how to make |
| horizontal bar graphs. |
| * [me] Don't always set Y-axis position automtically |
| * [me] Add Text::SetAngle() as synonym for SetOrientation() |
| Added SetLabelSide() as synonym for SetlabelPos() |
| * [me ]Make it possible to manually specify the alignment of the textstring |
| for the title position. This makes title looks nicer with horizontal |
| bar graphs. |
| * [me] Allow Y-axis labels to be at an angle |
| [14-May-2002] JpGraph 1.6.3 |
| =========================== |
| Changes/Additions: |
| * [me] Added functionality to make AccBarPlot::SetAbsWidth() work in |
| jpgraph_bar.phps |
| * [me] LinePlot::SetColor() no longer sets the color of the plotmark. |
| The problem that some people had was that if you set the mark color |
| specifically first and then unsuspecting called SetColor() for the |
| line the color for the plotmark circumference would also be set making |
| it look like the PlotMark::SetColor() didn't work. |
| * [me] Improved the functionality of GanntGraph::SetDateRange() to make |
| it possible to display a section of the graph. |
| (In previous version it was a checked error if you tried to plot |
| a graph where any activity bar was outside the specified area. |
| This is now changed to only cap the bars to the area. |
| This makes it more suitable to handle big gantt charts |
| which now can be split into several images to show different |
| parts of the projects) |
| * [me] Added GanttScale::SetWeekStart() to set the start of week to an |
| arbitrary day. For example SetWeekStart(0) will make the weeks start |
| on Sunday, SetWeekStart(1), Monday and so on. |
| * [me] Fixed a rounding error in Gantt chart that could cause the week |
| start day to off by one. |
| * [me] Modified the Min() and Max() methods for AccLineBar's to avoid |
| them overestimating the max value. (Basically now using the same |
| methods as in AccBarPlot) |
| * [me] Added missing code to do percentage calculation for 3D Pies so |
| they work the same way as the 2D Pies. |
| * [me] Added error check for the case where the image is so small that |
| the available plot area becomes to small. |
| * [me] Compensate for a PHP bug (#12474) in strtotime() which can affect |
| Gantt chart so that the same month name is shown twice. |
| See http://bugs.php.net/bug.php?id=12474 |
| * [me] Compensate for the documented shortcomming in my |
| 3D Pie algortitm whereby a small exploded slice close to 270 degrees |
| get's slighthly nagged at tha base due to the fact that the z-order |
| stroking algorithm is only perfect if the slices are not exploded. |
| [20-April-2002] JpGraph 1.6.2 |
| ============================= |
| Changes/Additions: |
| * [me] Slightly adjusted LinearTicks::Stroke() to better handle som |
| potential rounding problems. |
| * [Thomas George] Added LinePlot::AddArea() which makes it possible |
| to just fill part of a line plot (a part that is specified with a |
| start and end x-point) |
| * [Thomas George] Fixed bug with missing coordinate when using filled |
| line plot with step style. |
| * [me] Added client side image maps to scatter and line plots |
| * [me] Fixed problem with warning "IMG_ARC_CIRCLE not defined" when |
| running on GD 1.x |
| * [me] Removed test with is_null() in jpgraph.php to make JpGraph 1.6.2 |
| work with older versions of PHP (especially 4.02). |
| [07-April-2002] JpGraph 1.6.1 |
| ============================= |
| Changes/Additions: |
| * [me] Modified autoscaling for the case where all values are equal to |
| make the min/max difference larger. |
| * [me] Fixed bug in 3D pies for certain data values |
| * [me] Fixed bug with images maps assuming that slices |
| where order anti-clockwise and the new pie algorithm did them |
| clockwise. |
| * [me] Added subtitle to Pie and Pie3D graphs. |
| [02-April-2002] JpGraph 1.6 |
| =========================== |
| Changes/Additions: |
| * [me] Changed license to QPL |
| * [me] Completely rewritten algorithm for 3D pies which gives MUCH better result. Will |
| also allow exploded 3D pies. |
| * [D. Reinbach] Better handling of filling line plot with negative |
| values |
| * [me] Added LinePlot::StrokeDataValue() for easy handling of plotting |
| data point values. |
| * [Gyozo Papp,me] Real locales for Gantt chart. The locales now take a |
| proper locale string (e.g. "en_UK", or "sv_SE") to get the real |
| locales from the system. Note that this breaks the sc compatibility |
| * [me] Removed jpgraph_dir.php and moved the directory settings back in |
| jpgraph.php due to problems in PHP with nested includes and search |
| paths. |
| * [me] Added possibility to show values for scatter plot by |
| refactoring value support back into jpgraph.php Plot() class. This |
| makes it easy for all subclasses that uses Plot() to add display |
| value support. |
| * [me] Added possibility to use X-coordinates in Error plots |
| * [me] Fixed missing LogScale::SetXLabelOffset(). This made it |
| impossible to use linear plots with a log x-scale !!! |
| * [me] Fixed bug so possible Y2 plots are also taken into account when auto |
| scaling the X-axis. This could otherwise couse plots outside the |
| scale when using Y and Y2 plots where Y2 plots had more data values. |
| * [me] **********!!SC BREAK!!************** |
| Aligned the way values are displayed on Bar graphs with line and |
| scatter plots. The values to be displayed for these plots are now |
| all accessed through the "value" property of the plot. For example |
| $myBarPlot->value->Show(); |
| instead of the previous |
| $myBarPlot->ShowValue(); |
| * [me] **********!!SC BREAK!!************** |
| Aligned the way values are displayed in Pie plots with line and |
| bar plots. You know use the "value" property in exactly the same way |
| as in bars and lines. |
| * [me] **********!!SC BREAK!!************** |
| Aligned the way values are displayed in 3D Pie plots with line and |
| bar plots. You know use the "value" property in exactly the same way |
| as in bars and lines. |
| * [me] Added possibility to display individual values in an |
| accumulated bar graph in addition to the overall accumulated |
| value. This is done as usual through setting the individual bars |
| value property to what you want (size, color, format and so on) |
| * [me] Added another default error handler which is image based to |
| make it easier to see error messages when images are included |
| in a page. This is now the default error handler. |
| * [me] Added possibility to specify the location of the X-Axis |
| to the top of the graph by using xaxis->SetPos("max") also |
| added new Example topxaxisex1.php to demonstrate this feature. |
| * [me] Added more 3D pie examples to demonstrate new functionlity. |
| [01-March-2002] JpGraph 1.5.3 |
| ============================= |
| Changes/Additions: |
| * [me] Make it possible to use JpGraph 1.5.3 with GD 1.8.x. In 1.5.2 I was |
| using a function only available in GD 2.x. |
| [29-Feb-2002] JpGraph 1.5.2 |
| =========================== |
| Bug fixes: |
| ---------- |
| * [me] Released the correct 3D pie file (By mistake I mixed the stable version with |
| the development branch for 2.0 in the 1.5.1 release just to prove |
| that I'm still human :-) |
| * [me] Fixed out of bounds error when using shadows for bar graphs |
| with 0 value |
| * [me] Fixed typo in DisplayValue::SetFormat() |
| * [me] Fixed potential array out of bounds error in Plot::Min() and |
| Plot::Max() |
| * [me] Fixed misplaced ')' in string construction in call to |
| JpGraph error. |
| Changes/Additions: |
| ------------------ |
| * [me] Added possibility to use "auto" file name when stroking |
| directly to a file. |
| * [me] Added tag 'title' to the image maps to make for better |
| compatibility with Mozilla. |
| * [me] Moved class LineProprty to jpgraph.php from jpgraph_gantt.php |
| since it can be used in other modules as well. |
| * [me]Added Text::GetTextHeight() which differs from |
| Text::GetFontHeight() in that it takes the total text height |
| (possible multiple lines) into account. |
| * [me] Added Image::FilledArc() |
| * [me] Added RotImage::SetTranslation() |
| Added RotImage::Circle() |
| Added RotImage::FilledCircle() |
| Added RotImage::Arc() |
| Added RotImage::FilledArc() |
| [11-Feb-2002] JpGraph 1.5.1 |
| =========================== |
| * [me] No longer treat a not set $y[0] value as an explicit error. Instead |
| silently set $y[0] to 0. |
| * [me] Changed "include" to "require" in jpgraph.php when including |
| jpgraph_dir.php. This seems to fix the strange problem whereby |
| the constants defined in jpgraph_dir.php didn't have a correct |
| value in jpgraph.php. |
| * [me] Fixed problem with correctly drawing of bars when all bars |
| are negative. (Previously the baseline wasn't correctly handled |
| since min/max values needs to be mirrored for negative bars) |
| Note: Funny this problem has gone unnoticed so long. |
| * [me] Fixed problem with doing gradient fill for negative bars. |
| * [me] Fixed problem with autoscaling when there is a very small |
| difference (< 0.00001) between min and max and when both min and max are |
| negative. This might happen if you have a single negative value. |
| * [me] Added labels for line graph. Each point my now also optionally |
| display it's value on a line graph. Value are controlled trough |
| class DisplayValue and it's instance in LinePlot. |
| LinePlot->value->Show(), |
| LinePlot->value->SetColor(), |
| LinePlot->value->SetFont(), |
| LinePlot->value->SetMargin(), |
| LinePlot->value->SetFormat(), |
| [27-Jan-2002] JpGraph 1.5 |
| ========================= |
| * [me] Fixed misnamed xmin variable in Min() for acc bars |
| * [me] Added possibility to specify paragraph alignment for |
| multi line text, i.e the text can be left,right or center aligned |
| within it's bounded box. The lignment is set by the new method |
| Text::ParagraphAlign() |
| * [me] Changed position specification for text so that if the position |
| is specified in range [0,1] it is interpreted as fraction of image |
| height width and otherwise as absolute pixels. |
| * [me] Added possibility to specify pie size (radius) both as a fraction and |
| absolute size in pixels. |
| * [me] Added possibility to tweak color specification by adding a |
| saturation percentage, i.e you can specify color as "red:0.65" |
| which means 65% of the red value (in other words 35% darker). |
| * [me] Tweaked the estimation of number of segments to approximate an |
| arc in Image::CakeSlice. |
| [17-Jan-2002] JpGraph 1.5beta2a |
| =============================== |
| * [me] Fixed typo in Max() calculation for accumulated bar graphs |
| which caused it to return wrong value. |
| * [me] For Min() calculation for acc bars graphs take the user |
| specified ymin into account. |
| * [Peter Svistunov, me] Added Cyrillic unicode support through the |
| global define LANGUAGE_CYRILLIC. This is also the start of a |
| generic support for Unicode languages through the LanguageConv |
| class. |
| [15-Jan-2002] JpGraph 1.5beta2 |
| ============================== |
| * [me] Rewrite of the pie-chart drawing algorithm. This version |
| is slightly slower but avoids using GD floodfill function. This |
| fixes problems with small slices not being filled completely. As |
| an added bonus it is now possible to explode (and specify the |
| explode radius) for all slices. It is also possible to draw the |
| pie without having internal borders between the slices as well |
| as turning on/off the border surronding the pie. |
| * [me] Added graphic primitive CakeSlice() to the Image class. |
| Used to simplify pie-drawing. |
| * [me] Added more generic error handling. It is now possible to |
| install your own error object with |
| JpGraphError::Install(<name of error object>) |
| The default error handler will just abort execution. |
| * [me] Security whole in utility script for displaying source |
| and image in frames fixed. |
| * [Cedric Scheyder] Actively ignore hours in calculating Max/Min |
| values for dates in Gantt charts to avoid problems in autoscaling |
| when users specify start and end dates down to hours. |
| * [Rick Widmer] Fixed problem in calculating min/max value when first |
| Y-value was non-numeric. |
| * [me] Fixed calculation of width and height of text with multiple lines. |
| Multiple text lines (text blocks) should now be almost fully supported. |
| [16-Dec-2001] JpGraph 1.5-BETA |
| ============================== |
| * Take "\n" into (some) account when calculating string height and width |
| Text output now supports multiple lines better. |
| * [me] Removed reference to global PHP_SELF, use HTTP_SERVER_VARS array |
| instead. This makes JpGraph working with 'register_globals' turned |
| off. |
| * [me] Added some rudimentary check that GD is enabled before trying to |
| run JpGraph. |
| * [me] Fixed silly cut-and-paste bug in AccBarPlot::Max() which could |
| cause to small max values to be returned |
| * [me] Added property 'title' to PlotMark. The title is printed in the center |
| of the plotmark. |
| * [DanNY (dulcis28@hotmail.com)] Added JpGraph Logo. (Thanks!) |
| * [me] Added jplintphp.php, jpgendoc.php, jplintdriver.php which are |
| parsing, documentation and pretty printing tools I use to help |
| me to documentation and find unused code. |
| Tthat does some simple static analysis on PHP for silly mistakes |
| that I do (Like using instance variables without qualifying them |
| with "$this->" ) The tool also warns about unused instance variables. |
| Since it also parses the classes and methods I use it to generate |
| the documentation skeleton for the reference section. |
| * [me] Added Gantt chart funcionality, jpgraph_gantt.php . See |
| Gantt tutorial for help on usage. |
| * [me] Added new Gantt tutorial |
| * [me] Added BKIMG_CENTER, possibility to center the background image. |
| * [me] Timeout function now also aplies when you generate an image |
| off-line, i.e if the imagefile exist and is within the time window |
| now file will be written. |
| * [Rasmus Lerdorf] Added patch to make background images work with GD 2.x |
| N.B GD 2.01 has bugs in handling TTF font with truecolor images which |
| are fixed in 2.02 but that has (of this writing) still not been officially |
| released. GD 2.x support in JpGraph is still to be considered experimental. |
| * [me] Fixed some potential rounding errors in 2D Pie plot which in some |
| circumstances might have caused a flood fill to escape. Also added check |
| to better handle very small slices so we don't try to do a fill |
| on the border edge. |
| * [me] Slightly changed the internal design for band patterns. |
| They are now created by a factory class instead. This makes it much easier |
| to re-use and have maximum code reuse. |
| * [me] Factored out some functionlity from Graph::Stroke() to make it possible |
| to re-use some code in GanttGraph::Stroke() |
| * [me] One more instance when PHP surprised me by thinking 0 == "-" aarrghhh |
| Now I think (knock on wood) all problems with data points=0 should be solved |
| * [me] Added '&' to the assignment in Graph::Add() This now lets you specify changes |
| for lines, plots even after they been added to a Graph. But I'm not sure if this |
| is really such a good ide because you will have problem if you write code |
| like |
| for( .... ) { |
| $myplot = new LinePlot(.....); |
| $graph->Add($myplot); |
| } |
| Since this will not work the way you think (why?) Because the same |
| reference to the variable $myplot will be used for all additions and |
| hence the graph will only have multiple instances of the last added |
| LinePlot(). Have to think of this and what is the best way. (I will |
| probably never get used to PHP references....) |
| [11-Nov-2001] JpGraph 1.4 |
| ========================== |
| Bug Fixes: |
| ------------------------------------------------------------------------------------- |
| * [me] Enabled E_NOTICE warnings in my PHP installation and found a couple of |
| glitches (harmeless out-of-bound in two loops) which is now corrected. |
| * [me] Fixed problem in line plots where y-value==0 wasn't drawn. (Once again |
| bitten by the fact that in PHP the following is true: ""==0) |
| * [me] Fixed color specification for bars when initialized as an array of colors |
| * [me] Fixed color of bars using shadow which was advertedly set to shadow color |
| * [me] Fixing incorrect color specification for legends using bars with color arrays |
| * [me] Add check for sum=0 in pie plots to avoid divide by 0 problem |
| * [me] Changed the stroke orderd for FilledRectangle() so that the shadow doesn't |
| overwrite a line with weight > 1 |
| * [me] Fixed incorrect calculation of font height for titles which cause the |
| subtitle to be to close to the title. |
| Additions: |
| ------------------------------------------------------------------------------------- |
| * [me] Added depth parameter (DEPTH_FRONT, DEPTH_BACK) for gridlines |
| Graph::SetGridDepth() |
| * [me] Added possibility to add static horizontal and vertical band with a |
| pattern in the plot area. Graph::AddBand() Supports solid, diagonal, |
| stright line, 3D-plane crosses (both diagonal/vertical) patterns. |
| Graph::AddBand() |
| * [me] Added possibility to have static lines in the plot. This is now implemented |
| with new class PlotLine and two new functions Graph::AddLine(), |
| * [me] Added symbolic constants to specify background image types |
| BGIMG_COPY, BGIMG_FILLPLOT, BGIMG_FILLFRAME |
| * [me] Added extended label formatting through either |
| Axis::SetLabelFormatString() C-style formatting string |
| or |
| Axis::SetLabelFormatCallback() A callback function that are given the value to be displayed |
| and should manipulate the value as it likes |
| The use of the old style digit precision variable will be deprecated from next version. |
| * [me] Added error check if supplied Y-data has unspecified value at index 0 to avoid |
| out of bounds error when corrupted data is sent in to JpGraph. |
| * [me] Added possibility to specify image depth for gridlines. You can now specify |
| Graph::SetGridDepth() as DEPTH_FRONT or DEPTH_BACK. Depending on if you want |
| the gridlines at the back of in front of your plots. |
| * [me] Added possibility to specify Cache file name as "auto". In this case the |
| image file name will have the same name as the scriupt that generates the |
| image with the extension of the automtically generated graphic format. |
| NOTE: You will get the wrong extension using this feature at the same |
| time as specifying a different graphic format thne the automatically choosen |
| one. |
| * [me] Added some more advanced examples for impuls drawings impulsex3.php and |
| impulsex4.php |
| * [me] The values on top of bars can now be at an angle and the horisontal |
| position now account for if a shadow is present. |
| * [me] Added filename to Graph::Stroke() which makes it easy to output an image |
| directly to a file _without_ streaming it back to the browser. Usefull for |
| batch processing |
| * [me] Added new tutorial for bar graphs |
| * [me] New scale type "int". This gives a normal linear scale but restricts |
| ticks (and labels) to integer values. Can be used for both X and Y scales. |
| * [me] Added subtitle to graph |
| * [me] Added possibility to specify an array of X-coordinates with bar plots to |
| position individual bars on the X-scale. Makes it much easier to combine |
| bar plots with other types of plots, (line, scatter etc) |
| * [me] Extended utility adjimage.php to allow it to manipulate color saturation. |
| * [me] Added Image::AdjSat() to allow manipulation of the color |
| saturation in the image. This also makes it very easy to change the image |
| to greyscale (just set saturation=-1). |
| Extended Graph::AdjImage() and Graph::AdjBackgroundImage() |
| to include new parameter for saturation value. |
| * [me] Added BarPlot::SetAlign() which makes it possible to align |
| bars relative the tickmark for linear and int scale |
| * [me] Added possibility to absolutely set the width of bars. This will |
| override the automatically decided with based on the scale and tick distance |
| Changes: |
| ------------------------------------------------------------------------------------- |
| * [me] Legend color for scatter plots now becomes the fill color of the mark |
| * [me] Impulsplots now anchors at Y-value = 0 if the y-axis contains both negative |
| and positive values. Otherwise it will go to the lowest value on the Y-axis. |
| * [me] Bar shadows is now connected to bars to make for a stronger 3D effect. |
| * [me] Removed all deprecated references and usage of FONT0, FONT1, FONT2. Note |
| You can no longer use these. Instead use FF_FONT0, FF_FONT1, FF_FONT2 etc |
| * [me] Text scale now starts default labelling at 0 |
| * [me] All plots internally adjusted to start at default X-coordinate 0 to harmonize better |
| with X-scale. |
| * [me] Graph->Stroke() now just returns instead of exit() |
| * [me] Removed flag argument for BarPlot::SetShadow() |
| * [me] Bar plots are know by default filled with lightblue |
| unless otherwise specified. |
| * [me] Changed the way bars are positioned for linear and integer |
| scale for maximum flexibility when mixing barplot with other |
| plots. |
| * [me] The ALT strings for all image maps now uses printf() syntax to display |
| the actual value. If you have used this feature you must update your |
| ALT strings, for example "val=%v" must become "val=%d" or whatever format |
| you choose. |
| * [me] Changed the formatting of bar graphs by changing the framework |
| so that labels on the x-axis using a text scale is now independent |
| on the tick marks. |
| This makes it possible to have the labels centered under each bar but have |
| the tickmarks between the bars as most other commercial graph packages |
| format these typw of graphs. Introduced Axis::SetTextLabelsInterval() |
| Effects jpgraph.php, jpgraph_log.php and jpgraph_bar.php |
| * [me] Renamed Axis::SetTextTicks() to Axis::SetTextTicksInterval() to make the name |
| more descriptive. The old name is deprecated from this version on but will still |
| work until 2.0 to keep compatibility. |
| * [me] Cleaned up implementation of pie3d so it now inherits from pie to avoid |
| a lot of duplicated code and easier maintainance. (A good example of the real |
| life OO programming where you might not see the similarities between two classes |
| until you fully implement them.) File size of jpgraph_pie3d.php has shrunk by |
| roughly 40% |
| [23-Sep-2001] JpGraph 1.3.1 |
| =========================== |
| Additions: |
| * [Michael Anthon] Added client side image maps to 3D pie plots |
| * [me] Added possibility to better control the labeling of pie graphs with an optional |
| label formatting string PiePlot::SetLabelFormat(), PiePlot::SetLabelType() |
| This also makes it possible to have labels with the absolute value and not only the |
| percentage. (same with pie3d) |
| * [me] Added formatting capabilities for legends on pie and pie3d graphs. Can have the value |
| automtically included (Se Examples/pieex6.php) |
| * [me] Added some more examples, negbarvalueex1.php, scatterlinkex2.php, pie3d_csimex1.php |
| pieex6.php |
| Known bugs and omissions: |
| - Client side image maps does not currently handle exploded pie graphs (just |
| normal pie graphs. |
| Bug fixes: |
| * [me] Fixed problem with positioning the displayed values for negative bars |
| * [me] Fixed shadow for negative bars |
| * [me] Fixed problem in Plot::Min(), PlotMax::Max() whereby zeros where not counted |
| towards minimum since in PHP 0=="". This could sometimes cause strange autoscaling. |
| * [Vitaly E. Ashmarin] Wrong arguments to imagejpeg() for combination of specified |
| image quality and filename = "" |
| * [John Milne] BarPlot::SetFillColor() fixed glitch in loop variable |
| [13-Sep-2001] JpGraph 1.3 |
| ========================= |
| Note: I have to the best of my memory tried to give credit where |
| credit is due. Howevever, since ver 1.2.2 I have received over 2000 mail about |
| JpGraph with Questions/Suggestions/Improvments (and a few bug fixes) etc and |
| I might have missed some in the process of going through these mails. The |
| fault is completely my own and if you recognize some idea I have implemented |
| something which you think you should have credit for please drop me a note and |
| I will adjust the add you to the change notes. |
| Known bugs and omissions: |
| - The automatic value on bar graphs does not work well with |
| negative bar graphs. (Quite easy to fix though..) |
| - Client side image maps does not currently handle exploded pie graphs (just |
| normal pie graphs. |
| IMPORTANT NOTICE: |
| * SC (SOURCE COMPATIBILITY) BREAK !: If you want to rotate the image the parameter |
| is no longer supplied directly in the call to Graph() but rather as a method |
| call Graph::SetAngle(). I decided to make this SC break since I judged it more |
| natural to supply the timeout value just efter the specified cache-file name |
| in the Graph() call. Hopefully this will not hit to many people since my hunch is |
| that few people uses the rotate function and it's very easy to fix those script |
| that does so. |
| Bug Fixes: |
| * [michael@anthon.net] Corrected behviour of accumulated bar graph so it now |
| diffrentiate between the accumulated positive and negative values. |
| * [marko@fly.srk.fer.hr] Fixed Max() calculations for accumulated bar graphs |
| where my original code was a little bit sloppy. (I simply took the max for |
| each plot and added those and this might be more then the real maximum.) |
| * [m.purgar@extracom.de] Spotting an incorrect "jpg" in the image where it should |
| have been "jpeg" |
| * [adam.blomberg@euroseek.net,patrik.johansson@euroseek.net] 3D-Pie filling |
| problem for small slices due to the discrapency between GD arc() and the |
| JpGraphs purely mathematical definition of an ellipse. |
| * [delorme.maxime@free.fr] 2D-Pie Floodfill might "escape" for very small values of slices. |
| * [et.al] Improved handling of 0:s vs "" values. This was necessary since PHP treats |
| 0 as "" the same in a number of situations and JpGraph needs to diffrentiate these |
| two cases. This caused 0 data values to be treated as null values and not be inluded |
| in (for example) autoscaling consideration. |
| Additions: |
| * [me] Added new global constant USE_CACHE which makes it possible to disable |
| writing to the cache even if a filename is supplied in th Graph::Graph() method. |
| * [me] Added LinePlot::SetStyle() to make it possible to make dashed, dotted etc |
| lineplots. (See example1.2). Also adjusted legend to display the same style in |
| the legend. |
| * [michael@anthon.net, me] Added client side image maps for all types of bars |
| and 2D pies with possibility to have the actual value shown in an ALT-tag. |
| * [me] Added drop shadow (or rather "right-up" shadow) to bar graphs BarPlot::SetShadow() |
| * [me] Added possibility to have the actual value of bar graphs displayed at top of graphs |
| via BarPlot::ShowValue(), BarPlot::SetValueFont(), SetValueMargin(), SetValueColor() |
| The format of the value is specified according to standard C printf() string formatting |
| i.e. "val=%d" will for example print a string "val=13" |
| * [me] Added possibility to adjust brightness and contrast for background image |
| via the Graph::AdjBackgroundImage() method. |
| * [me] Added possibility to adjust brightness and contrast in the finished image |
| via the Image::AdjBrightContrast() method. |
| * [me] Added possibility to just generate an image to a file and not stream |
| it directly back to the browser. Added parameter $aInline to Graph::Graph() |
| * [me] Added timout for cache, i.e if the image in the cache is older then |
| the specified number of minutes (=0 never re-generate, -1 always regenerate) |
| then re-generate the image. Just specify a timeout in minutes with a call: |
| $mygraph->cache->SetTimeOut(10) |
| * [me] Added possibility to use logarithmic scale for SpiderPlots. This also resulted |
| in a little bit of internal cleanup in jpgraph_spider.php. |
| * [me] Added SetWeight() method to class Ticks() for control of line thickness for ticks |
| * [me] Added SetMarkColor method to class TIcks() which lets you specify different |
| colors for major and minor tick marks. |
| * [me] Added method RelTranslate() to LinearScale() and LogScale() classes which is used |
| in Spider class. This makes a world to screen relative translation. |
| * [me] Added possibility to link data points in a scatter plot with lines |
| by the addition of method ScatterPlot::SetLinkPoints() |
| * [me,john.milne@one2one.co.uk] Added possibility to have individual colors of |
| bars in bar graphs by having BarPlot::SetColor() accept an array as argument. |
| * [sergio@alsernet.es] Make it possibly to have x-tick labels to consist of two lines |
| by inserting a "\n" separator in the text. |
| * [CK1@wwwtech.de] Adding JPEG quality setting. This is done by adding |
| a method SetQuality() to the img class. After creating a graph this can then |
| be used as $mygraph->img->SetQuality($some_qvalue). |
| Currently this only affects JPEG images. |
| * [delorme.maxime@free.fr] Possibility to use different grace value for top and bottom |
| of graph and not just a single value as in 1.2.2 |
| Changes: |
| * [me] Changed group/permission handling for created files to better adjust itself |
| to the way the local Apache user is setup |
| * [me] The default for spider graphs is now NOT to be filled |
| * [me] Allow all datapoints to be 0 which will set the scale to [0,1] |
| * [me] Removed the need for a DIR_BASE variable |
| [29-Apr-2001] JpGraph 1.2.2 |
| =========================== |
| Bug fixes: |
| * Removed reference to non-existent property 'bypass' in class RotImg |
| * Changed to allow the last X-gridline to be drawn (comparison with limit was '<' |
| where it should have been '<=' ) |
| Additions: |
| * Added possibility to use background image |
| * Added possibility to use approximate color through the "USE_APPROX_COLORS" |
| constant |
| * Handling of diffrent form of "null values" for line graphs. An y-value |
| can now be "" or "-". In the first case (a true null value) this mark |
| will cause a disruption in the line graph to indicate that the value |
| is undefined. In the other case specifying the value as "-" will cause |
| the value to be ignored bu the line will still be drawn between the |
| previous data point and the following. Neither of these cases will have |
| any mark drawn. |
| * Added a fatal warning when no more colors can be allocated for the chosen |
| graphic format. |
| Changes: |
| * "Downgraded" anti-aliasing algorithm to use fewer color levels |
| in the transition to avoid using up to much of the color palette |
| * Cleaned up some of the code to not rely on PHP default initialization |
| of variables. This will help those who have got warnings when they |
| have had all error reporting enabled in php.ini (E_ALL) |
| * Legends now show the plot mark (if defined) instead of just a square of |
| the right color. |
| Acknowledgements: |
| * Thanks to kevin@pricetrak.com for suggesting the treatment of |
| pure NULL values. |
| * Thanks to luca_n@hotmail.com for getting my attention to the warnings |
| caused by relying on PHP default initialization of variables. |
| (My installation had E_NOTICE disabled, hence I never got those warning myself.) |
| [29-Mar-2001] JpGraph 1.2.1 |
| =========================== |
| Bug fixes: |
| * When min and max values for autoscaling was equal this resulted in trying to calculate |
| log10(0) = INF resulting in an infinite loop in LinearTicks::Stroke() |
| * When autoscaling was used with only one data point it tried to calculate log10(0) = INF |
| resulting in an infinite loop |
| * fopen("xxx","r") should be fopen("xxx","rb") causes problems on windows system with IIS5 |
| * JPG streaming function was incorrectly called "imagejpg" should be "imagejpeg" (see the difference?) |
| * Non existent color name in jpgraph_pie.php |
| * Removed all deprecated forced references in function calls |
| * The width of the surrunding box was not calculated correctly for internal bold font |
| Additions: |
| * Color themes for pie graphs |
| * Beta release of 3D pie graphs |
| * Added DIR_BASE as constant to make it possible to use one system wide copy |
| of JpGraph. NOTE: This must be set to the directory where JpGraph is installed. |
| Acknowledgements: |
| * (ck1@wwwtech.de) (and a russian guy which I unfortunately lost the name of) |
| for reporting the imagejpg spelling mistake |
| * (ales.gregor@zps.skoda-auto.cz) for finding the binary file problem with IIS |
| * Several people have reported the problem with autoscaling when all Y-values |
| were equal. Thanks to you all for acting as my privet QA team! |
| [18-Mar-2001] JpGraph 1.2 |
| ========================= |
| Additions: |
| ---------- |
| * Added "BRAND_TIMING" which give possibility to brand each image generated with |
| the time (in ms) it took to generate the image. |
| * Added Gradient Fill for bar graphs, The gradient fill allows 6 different styles. |
| * Added Anti-aliasing for lines. Note drawing anti-aliased lines is 7-10 times |
| slower then "normal" lines! |
| * Added full TTF support. this means an internal SC break (Source Code Break). Normal JpGraph |
| script should not be affected if you have used only publized "public" frunctions. The SC break is |
| to allow uniform treatment of both internal fonts and TTF. This has been achieved by changing |
| the parameter list for SetFont(). However, backward compatibility with the old naming conventions |
| for internal fonts are kepot, e.g. SetFont(FONT1_BOLD) still works but is deprecated and will not |
| be valid from 2.0 |
| * Added possibility to control font for title of Spider Axis through the added |
| property 'title' to the axis in the spider graph. |
| * Added 'SetColor()' in pie graphs as a shortcut to SetMarginColor() to set the background color |
| * Added possibility to draw X-axis labels at arbitrary angle. Internal fonts only supports |
| horizontal and verical. |
| * Added possibility to draw boxed text at an angle |
| * Added possibility to have different colors for axis and the labels on the axis by the addition |
| of extra parameter to SetColor() |
| * Added 350 more named colors. |
| * Added canvas "fake" graph to make it easy to draw arbitrary graphics |
| * Added SetCenter() method for line graphs. |
| * Added SetGrace() for autoscaling purposes. |
| Changes: |
| -------- |
| * If you use a text-scale for X-axis the default labels now start at 1 instead of 0 since this is |
| actually a counting scale and it makes more sense to start at 1. |
| * Improved handling of bar-graphs with negative values. |
| * Updated existing examples to use new format for SetFont() |
| * Made it a critical error to specify a non existant font |
| * Changed so that orientation for Text() is now given as an angle, i.e. SetOrientation(45). Old |
| style of using SetOrientation("v") (for vertical) is deprecated. But will work until V2 |
| Bug fixes: |
| ---------- |
| * Improved handling of computational effects on small values in scaling where a rounding error might cause the |
| last label not to be drawn. |
| * The position for the title of X-axis could in some cases be slightly different in first |
| and second pass due to incorrectly determination of the X-axis labels font height. |
| * Specifying an minimum Y-value for Y-axis on bar graphs could on rare occasions (combination |
| of scale values and specified density of autoscaling ticks) cause a gap between the bottom of |
| each bar and the X-axis. |
| [18-Feb-2001] JpGraph 1.1 |
| ========================= |
| Additions/Changes: |
| ------------------ |
| * Added Spider graphs |
| * Added Pie graph |
| * Added Scatter (and impuls) graphs |
| * Added possibility to rotate plots an arbitrary angle |
| * Added step style rendering to lineplot |
| * Added Breseham circle drawing which gives better visual apperance |
| then the built in Arc() in GD (on the expense of CPU and performance) |
| * Improved Polygon and Rectangle drawing so that it will use line weight settings |
| * Improved the visual appearance of lines with weight>1 by correctly calculating |
| (angle wise) the endpoints and using a filled polygon to draw the line. |
| Unfortunately it would require some real improvements in the GD library to really improve |
| the visual appeance of lines with weight>1. This is as good as it gets without writing |
| a low level pixe-by-pixel correct plotting. With my method you get it to look visually |
| aestethic right in 90% of the cases with just 10% work. |
| * Added MARK_FILLEDCIRCLE as new mark type. Note that due too the poor performance of the |
| basic Arc() image primitive in PHP4 the circles isn't perfect circles, they tend to be a |
| a little bit flat at multiples on PI/2. |
| * Added the possibility to have a separate fill- and line- color for marks |
| * Moved Class PlotMark from jpgraph_line.php to base in jpgraph.php since this class is also used |
| with scatter plots. |
| * Made it a critical error to try to use Text X-scale with specified X-data points. |
| Previously no warning was given for this non-defined state. (Using text scale with specified |
| points really doesn't make sense.) |
| * Made it a critical error to use unknown color rather than silently replacing it with black. |
| * Updated documentation to reflect added capability |
| Bug fixes: |
| ---------- |
| * Fixed minor bug in Line() in which it didn't update the last point for use with |
| subsequent LineTo() calls (forgotten $this->) |
| * Eliminated assumptions in DashedLine() that x1<=x2 and y1<=y2 eliminates the |
| potential pixel overshoot. |
| * Fixed a serious bug in Line plot when used with a specified X-scale (not the normal default) |
| since the X-coordinate wasn't read from the correct vector! |
| * Fixed a serious bug whe using as specified X-scale since the maximum value for a plot |
| wasn't correctly passed to the autoscaling. |
| Note: The reason that these two bugs haven't been discovered previously is the fact |
| that my test specs didn't include test cases to do with specified X-axis (I almost never ever use that). |
| This has now been corrected and added to the test suit. |
| * Fixed so the possible box around the plot area correctly honours the weight specified for it. |
| [05-Feb-2001] JpGraph 1.0 |
| ========================= |
| * Initial release. |
