React PieChart - ArrayStore

If you want to extend the functionality of a JavaScript array, place it into an ArrayStore. It provides an interface for loading and editing data, and allows you to handle data-related events.

jQuery
index.js
const fruits = [
    { fruit: 'Apples', count: 10 },
    { fruit: 'Oranges', count: 12 },
    { fruit: 'Lemons', count: 15 },
    { fruit: 'Pears', count: 20 },
    { fruit: 'Pineapples', count: 3 }
];

$(function() {
    $("#pieChartContainer").dxPieChart({
        dataSource: new DevExpress.data.DataSource({
            store: {
                type: 'array',
                data: fruits,
                onLoaded: function () {
                    // Event handling commands go here
                }
            },
            paginate: false
        }),
        series: {
            argumentField: 'fruit',
            valueField: 'count'
        }
    });
});
Angular
app.component.ts
app.component.html
app.module.ts
import { Component } from '@angular/core';
import DataSource from 'devextreme/data/data_source';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    fruits = [
        { fruit: 'Apples', count: 10 },
        { fruit: 'Oranges', count: 12 },
        { fruit: 'Lemons', count: 15 },
        { fruit: 'Pears', count: 20 },
        { fruit: 'Pineapples', count: 3 }
    ];
    pieChartDataSource = new DataSource({
        store: {
            type: 'array',
            data: this.fruits,
            onLoaded: function () {
                // Event handling commands go here
            }
        },
        paginate: false
    });

const pieChartDataSource = new DataSource({

        type: 'array',
        data: fruits,
        onLoaded: function () {
            // Event handling commands go here

    paginate: false

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

const fruits = [
    { fruit: 'Apples', count: 10 },
    { fruit: 'Oranges', count: 12 },
    { fruit: 'Lemons', count: 15 },
    { fruit: 'Pears', count: 20 },
    { fruit: 'Pineapples', count: 3 }
];

const pieChartDataSource = new DataSource({
    store: {
        type: 'array',
        data: fruits,
        onLoaded: function () {
            // Event handling commands go here
        }
    },
    paginate: false
});

export default function App() {
    return (
        <PieChart dataSource={pieChartDataSource}>
            <Series argumentField="fruit" valueField="count" />
        </PieChart>
    );
}

As you may notice, in the previous code, the ArrayStore 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 map objects from the array that underlies the ArrayStore, as shown in the following code.

jQuery
index.js
const fruits = [
    { apples: 10 },
    { oranges: 12 },
    { lemons: 15 },
    { pears: 20 },
    { pineapples: 3 }
];

$(function() {
    $("#pieChartContainer").dxPieChart({
        dataSource: new DevExpress.data.DataSource({
            store: {
                type: 'array',
                data: fruits
            },
            map: function (item) {
                const fruitName = Object.keys(item)[0];
                return {
                    fruit: fruitName.charAt(0).toUpperCase() + fruitName.slice(1),
                    count: item[fruitName]
                }
            },
            paginate: false
        }),
        series: {
            argumentField: 'fruit',
            valueField: 'count'
        }
    });

            <Series argumentField="fruit" valueField="count" />
        </PieChart>
    );
}
NOTE
Even if you have passed a JavaScript array to the dataSource property, the PieChart automatically places it into an ArrayStore wrapped into the DataSource that you can get with the getDataSource() method.
