React PieChart - OData Service

To bind the PieChart to data provided by an OData service, use the ODataStore.

jQuery
index.js
$(function() {
    $("#pieChartContainer").dxPieChart({
        dataSource: new DevExpress.data.DataSource({
            store: {
                type: 'odata',
                url: 'https://www.example.com/dataservices/odata/targetData',
                key: 'Id'
            },
            paginate: false
        }),
        // ...
    });
});
Angular
app.component.html
app.component.ts
app.module.ts
<dx-pie-chart [dataSource]="pieChartDataSource">
    <!-- ... -->
</dx-pie-chart>
import { Component } from '@angular/core';
import 'devextreme/data/odata/store';
import DataSource from 'devextreme/data/data_source';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    pieChartDataSource = new DataSource({
        store: {
            type: 'odata',
            url: 'https://www.example.com/dataservices/odata/targetData',
            key: 'Id'
        },
        paginate: false
    });
}
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxPieChartModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        DxPieChartModule
    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }
Vue
App.vue
<template>
    <DxPieChart :data-source="pieChartDataSource">
        <!-- ... -->
    </DxPieChart>
</template>

<script>
import DxPieChart from 'devextreme-vue/pie-chart';
import 'devextreme/data/odata/store';
import DataSource from 'devextreme/data/data_source';

const pieChartDataSource = new DataSource({
    store: {
        type: 'odata',
        url: 'https://www.example.com/dataservices/odata/targetData',
        key: 'Id'
    },
    paginate: false
});

export default {
    components: {
        DxPieChart
    },
    data() {
        return {
            pieChartDataSource
        }
    }
}
</script>
React
App.js
import PieChart from 'devextreme-react/pie-chart';
import 'devextreme/data/odata/store';
import DataSource from 'devextreme/data/data_source';

const pieChartDataSource = new DataSource({
    store: {
        type: 'odata',
        url: 'https://www.example.com/dataservices/odata/targetData',
        key: 'Id'
    },
    paginate: false
});

export default function App() {
    return (
        <PieChart dataSource={pieChartDataSource}>
            {/* ... */}
        </PieChart>
    );
}

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.

jQuery
index.js
$(function() {
    $("#pieChartContainer").dxPieChart({
        dataSource: new DevExpress.data.DataSource({
            store: {
                type: 'odata',
                url: 'https://www.example.com/dataservices/odata/targetData',
                key: 'Id'
            },
            paginate: false,
            // Take summer months only
            filter: [
                ['Id', '>=', 6],
                ['Id', '<=', 8]
            ]
        }),
        // ...
    });
});

A 1-Click Solution for CRUD Web API Services with Role-based Access Control via EF Core

If you target .NET for your backend API, be sure to check out Web API Service and register your free copy today. The Solution Wizard scaffolds an OData v4 Web API Service (.NET 6+) with integrated authorization & CRUD operations powered by EF Core ORM. You can use OAuth2, JWT or custom authentication strategies alongside tools like Postman or Swagger (OpenAPI) for API testing. The built-in Web API Service also filters out secured server data based on permissions granted to users. Advanced/enterprise functions include audit trail, endpoints to download reports, file attachments, check validation, obtain localized captions, etc.

To use the free Solution Wizard (which creates the Web API Service), run the Universal Component Installer from the DevExpress Download Manager and use our predefined template in Visual Studio 2022+.
