Bonjour à tous,


Sur un script MatLab 2015, je parviens à générer un graphique 3D avec BAR3. Seulement lorsque je veux y mettre les valeurs en abscisses cela n'affiche pas les valeurs attendues. Pouvez-vous me dire comment rédiger une syntaxe claire afin d'imposer des valeurs sur les axes du graphique ?

Merci.

Ce script ne permet pas d'afficher correctement les labels en x. Je ne comprends pas pourquoi.
