j'ai implémenté un graphique dans un canvas.
j'ai trouvé des exemples de graphique avec deux axes Y, mais avec la méthode plt.show().
étant novice, comment puis intégrer un deuxième le deuxième axe Y, dans le canvas?
merci pour votre aide

par contre, l'axe X n'est pas étendue sur toute la largeur. Cela provient de xlim
Comment puis afficher, sur l'axe X les tranches (exemple entre 0 et 5 --> 0 1 2 3 4 5)?
Comment indiquer une couleur des labels X --> ceci ne fonctionne pas --> ax.tick_params(labelcolor='#FF00FF', bottom=True)

merci pour votre temps
