Diagramme spline avec bandes de tracé
Voici un exemple de diagramme spline avec des bandes de tracé.
Nous avons déjà vu la configuration utilisée pour dessiner un graphique dans le chapitre Syntaxe de configuration Highcharts . Maintenant, comprenons un exemple de diagramme spline avec des bandes de tracé où des configurations / étapes supplémentaires sont prises.
Configurations
Configurez les bandes à l'aide de la propriété yAxis.plotBands. Définissez la plage de bande à l'aide des propriétés «from» et «to». Définissez la couleur de la bande à l'aide de la propriété 'color'. Donnez un style à l'étiquette de la bande en utilisant la propriété 'label'.
