Bonsoir, je suis entrain de coder une application qui permet de tracer des graphiques grâce à Matplotlib, j'ai juste une question lorsque je rentre le nom de mes graphiques (lignes 353 par exemple) avec une police différente, la police apparait tel quelle mais que dans le widget Entry or lorsque je lance le programme la police n'a pas été modifier (ligne 145) la valeur reçu via la variable String_graphic_1.get(). Comment faire pour afficher la taille et la police voulu sur matplolib ? Merci d'avance
