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]
            ]
        }),
        // ...
    });
});
