En agencant des rectangles imbriqu\u00e9s dans une zone d\u00e9limit\u00e9e unique, les cartographies codent les valeurs num\u00e9riques par la taille de la surface du rectangle, permettant aux utilisateurs d’\u00e9valuer les proportions relatives au sein de structures imbriqu\u00e9es complexes<\/em>\u2014par exemple l’utilisation de l’espace disque, le chiffre d’affaires du catalogue de produits ou les affectations budg\u00e9taires entre d\u00e9partements parent et enfants.<\/p>\n

Le fonctionnement des graphiques en cartographie<\/h2>\n

Dans Apache ECharts, les cartographies utilisent type : 'treemap'<\/code>. La s\u00e9rie attend un tableau structur\u00e9 en arbre o\u00f9 chaque objet contient un data<\/code> tableau o\u00f9 chaque objet contient un nom<\/code>, une valeur quantitative value<\/code>, et un tableau facultatif children<\/code> pour des niveaux imbriqu\u00e9s plus profonds.<\/p>\n

1. Configuration de base<\/h3>\n

Pour construire une cartographie de base, d\u00e9finissez un tableau de donn\u00e9es hi\u00e9rarchiques avec des \u00e9l\u00e9ments imbriqu\u00e9s children<\/code> et d\u00e9finissez type : 'treemap'<\/code> dans la configuration de votre s\u00e9rie :<\/p>\n

  • Activez les fil d’Ariane pour les hi\u00e9rarchies profondes\u00a0:<\/strong> Lorsqu’on affiche 3 niveaux ou plus d’imbrication, activez `breadcrumb: { show: true }` afin que les utilisateurs puissent facilement retrouver leur position et remonter rapidement.<\/li>\n
