DevExtreme jQuery/JS - OData Service
To bind the PieChart to data provided by an OData service, use the ODataStore.
jQuery
JavaScript
$(function() { $("#pieChartContainer").dxPieChart({ dataSource: new DevExpress.data.DataSource({ store: { type: 'odata', url: 'http://www.example.com/dataservices/odata/targetData', key: 'Id' }, paginate: false }) }); });
Angular
TypeScript
HTML
import { DxPieChartModule } from "devextreme-angular"; import "devextreme/data/odata/store"; import DataSource from "devextreme/data/data_source"; // ... export class AppComponent { pieChartDataSource = new DataSource({ store: { type: 'odata', url: 'http://www.example.com/dataservices/odata/targetData', key: 'Id' }, paginate: false }); } @NgModule({ imports: [ // ... DxPieChartModule ], // ... })
<dx-pie-chart [dataSource]="pieChartDataSource"> </dx-pie-chart>
As you may notice, in the previous code, the ODataStore is not declared explicilty. Instead, it is wrapped in the DataSource instance. That is because the PieChart requires pagination to be off in order to prevent data from partitioning. Other than that, the DataSource provides wide data-processing capabilities. For example, it can filter data.
