Soucis avec Core Plot
Bonjour,
Je travaille sur mon premier projet pour Iphone, je vais essayer de décrire mon problème.
J'utilise Core plot, ça fonctionne plutôt bien. Mais je suis devant un problème. Dans un controlleur de vue, j'ai mis en place un scrollview dans lequel je mets des vues contenant des graphiques.
Cela marche, j'ai bien mes graphiques, mais le datasource du core plot n'est pas exécuté au bon moment, ce qui fait que mes courbes ne s'affichent pas.
Voici mon code dans le viewdidload :
et voici mon makegraphe :
Et j'ai evidemment mes deux méthodes provenant du datasource :
Une précision :
J'ai mis des NSLog pour suivre l'exécution du process, et il execute tous les makegraphe et seulement ensuite les methode du datasource. Je pense que le souci vient de là , mais je ne trouve pas de solution.
Quand je ne mets qu'un seul graphique, cela fonctionne.
Merci d'avance pour votre aide.
