Je travaille avec des amcharts et je dois mettre des points à une date précise sans les joindre. J'ai essayé avec des guides mais je n'ai pas pu.Amcharts: Mettre des points sans ligne dans les graphiques en série
Mon tableau a un champ de catégorie: date max zoom est horaire.
Ceci est my chart avec les points rouges que j'ai dessinés pour vous montrer.
je les veux à une autre date, mais avec la même hauteur
Ceci est mon code:
