Le widget Treemap vous permet de visualiser les proportions d’un ou de plusieurs ensembles de données. Il peut afficher un seul ensemble de données avec les proportions correspondantes, ou plusieurs avec des proportions imbriquées.
Les liens de contexte sont activés par défaut, mais vous pouvez les désactiver si vous le souhaitez. Ils relient les widgets du dashboard à d’autres pages (dans Datadog ou sur des sites externes).
Si plusieurs groupes de données sont représentés simultanément, vous pouvez filtrer le widget pour afficher une catégorie spécifique et visualiser les proportions au sein de celle-ci.
Pour filtrer et mettre en évidence une catégorie spécifique, cliquez sur le rectangle extérieur correspondant à cette catégorie. Pour revenir à la vue précédente, cliquez sur le bouton Back en haut à gauche du titre du widget.
Pour accéder au menu contextuel, passez d’abord votre curseur sur une catégorie spécifique : il peut s’agir d’une catégorie imbriquée ou d’un groupe (Canada ou Canada > Chrome dans l’exemple suivant). Un bouton représentant trois petits points verticaux s’affichent alors en haut à droite. Cliquez dessus pour afficher le menu contextuel.
Lorsque vous visualisez le widget Treemap en mode plein écran, les options standard d’affichage en plein écran s’affichent.
Ce widget peut être utilisé avec l’API Dashboards.

}Comme pour le widget Treemap, il est possible d’utiliser le widget Graphique circulaire pour visualiser des proportions imbriquées. La principale différence entre les deux est que le widget Graphique circulaire affiche les proportions en tranches radiales, tandis que le widget Treemap affiche des rectangles imbriqués.
