Pie Markers

Documentation

This demo shows how to use markers of the «pie» type in the VectorMap. Values for pie markers are provided by the data field whose name is assigned to the dataField property.

Backend API
$(() => { $('#vector-map').dxVectorMap({ layers: [{ dataSource: DevExpress.viz.map.sources.world, hoverEnabled: false, }, { name: 'pies', dataSource: markers, elementType: 'pie', dataField: 'values', }], tooltip: { enabled: true, customizeTooltip(arg) { if (arg.layer.type === 'marker') { return { text: arg.attribute('tooltip') }; } return null; }, }, legends: [{ source: { layer: 'pies', grouping: 'color' }, customizeText(arg) { return names[arg.index]; }, }], bounds: [-180, 85, 180, -60], }); });
