Créé un nouvel histogramme avec les valeurs présentes dans $values.
$number représente le nombre d'histogrammes affichés en parallèle tandis que $identifier permet de spécifier où se situe l'histogramme courant.
$depth représente la profondeur de l'histogramme en pixels.
Le tableau $values doit être une liste de valeurs dans un tableau incrémental, c'est-à-dire dont les clés valent de 0 à n - 1 (où n est la taille du tableau).
