Angular Sankey - MongoDB Service
Use the third-party devextreme-query-mongodb extension to query data from MongoDB. This extension implements data processing on a server according to the DevExtreme UI components' protocol. To access the server from the client, configure the CustomStore as described in the Custom Sources article or use the createStore method. This method is a part of the DevExtreme.AspNet.Data extension. The following code shows how to use this method:
jQuery
$(function() { var serviceUrl = "http://url/to/my/service"; $("#sankeyContainer").dxSankey({ dataSource: DevExpress.data.AspNet.createStore({ key: ["from", "to"], loadUrl: serviceUrl }), sourceField: "from", targetField: "to", weightField: "amount" }) });
Angular
import { DxSankeyModule } from "devextreme-angular"; import CustomStore from "devextreme/data/custom_store"; import { createStore } from "devextreme-aspnet-data-nojquery"; // ... export class AppComponent { store: CustomStore; constructor() { const serviceUrl: string = "http://url/to/my/service"; this.store = createStore({ key: ["from", "to"], loadUrl: serviceUrl }) } } @NgModule({ imports: [ // ... DxSankeyModule ], // ... })
<dx-sankey [dataSource]="store" sourceField="from" targetField="to" weightField="amount"> </dx-sankey>
