DevExtreme Angular - JSON Data
To bind the PieChart to data in a JSON format, assign the data's URL to the dataSource option.
HTML
TypeScript
- <dx-pie-chart
- dataSource="http://www.example.com/dataservices/data.json">
- </dx-pie-chart>
- import { DxPieChartModule } from "devextreme-angular";
- // ...
- export class AppComponent {
- // ...
- }
- @NgModule({
- imports: [
- // ...
- DxPieChartModule
- ],
- // ...
- })
Note that you can also use a JSONP callback parameter supported by jQuery.ajax().
