Bonjour,
Je voudrais qu'en entrant une valeur dans le jTextField1, puis en cliquant sur le bouton jButton1, ça modifie la hauteur de la colonne 1 de mon histogramme (qui sera dans le jPanel1).
En réalité, il s'agit d'un stackedbarchart composé de huit colonnes, chacune divisée en 3 blocs.
Voici les codes:
package spu;
