Déterminez quelle axe existe dans le graphique avec JavaScript via C++

Le code d’exemple suivant montre comment utiliser Chart.hasAxis(axisType, isPrimary) pour déterminer si le graphique d’exemple possède un axe de catégorie et de valeur principal et secondaire.

Sortie console générée par le code d’exemple

La sortie console du code est affichée ci-dessous, elle montre true pour l’axe de catégorie principal et de valeur, et false pour l’axe secondaire de catégorie et de valeur.

  
Has Primary Category Axis: True  
Has Secondary Category Axis: False  
Has Primary Value Axis: True  
Has Secondary Value Axis: False
