L'exemple donné est simplifié. J'ai actuellement plusieurs plots avec les mêmes entrées de légende, et je ai voulu directement référencer la même cellule...
J'ai trouvé la solution ici :
https://forum.openoffice.org/en/forum/v ... =20&t=8991
C'est plus général. On peut aussi choisir les différents séries pour x (très utile!).
Code : Tout sélectionner
