Example
The following example shows how to create the Geo Point Map dashboard item, bind it to data and add to the existing dashboard.
Create data items (measures and dimensions) and use the DataItem.dataMember property to bind them to the existing data source’s columns. Then use the created measures and dimensions in the dashboard item to bind it to data.
After you add the created dashboard item to the Dashboard.items collection, call the Dashboard.rebuildLayout method to rebuild the dashboard layout and display changes.
// Use the line below for a modular approach:
// import * as Model from 'devexpress-dashboard/model'
// Use the line below for an approach with global namespaces:
// var Model = DevExpress.Dashboard.Model;
// ...
public createGeoPointMapItem() {
// Create data items for the GeoPointMap dashboard item.
var geoPointMapImport = new Model.Measure();
geoPointMapImport.dataMember("Import");
var geoPointMapLatitude = new Model.Dimension();
geoPointMapLatitude.dataMember("Latitude");
var geoPointMapLongitude = new Model.Dimension();
geoPointMapLongitude.dataMember("Longitude");
// Create the GeoPoint Map dashboard item and bind it to data.
var geoPointMapItem = new Model.GeoPointMapItem();
geoPointMapItem.name('geoPointMap');
geoPointMapItem.dataSource(excelDataSource.componentName());
geoPointMapItem.latitude(geoPointMapLatitude);
geoPointMapItem.longitude(geoPointMapLongitude);
geoPointMapItem.area("Europe");
geoPointMapItem.value(geoPointMapImport);
control.dashboard().items.push(geoPointMapItem);
// ...
control.dashboard().rebuildLayout();
}
