PieChart

The PieChart is a widget that visualizes data as a circle divided into sectors that each represents a portion of the whole.

Included in: dx.viz.js, dx.viz-web.js, dx.all.js

Module: viz/pie_chart

Export: default

You can create the widget using one of the following approaches.

jQuery

JavaScript

HTML

var fruits = [
    { fruit: 'Oranges', yield: 10, consumed: 7 },
    { fruit: 'Apples', yield: 15, consumed: 14 },
    { fruit: 'Bananas', yield: 9, consumed: 9 }
];
$(function() {
    $("#pieChart").dxPieChart({
        dataSource: fruits,
        commonSeriesSettings: {
            argumentField: "fruit"
        },
        series: [
            { valueField: "yield" },
            { valueField: "consumed" }
        ]
    });
});

<div id="pieChart"></div>

    <dxi-series valueField="consumed"></dxi-series>
</dx-pie-chart>

export class AppComponent {
    fruits = [
        // ...   
    ];
}

        ]
    }"></div>
</div>

angular.module('DemoApp', ['dx'])
    .controller("DemoController", function ($scope) {
        $scope.fruits = [
            { fruit: 'Oranges', yield: 10, consumed: 7 },
            { fruit: 'Apples', yield: 15, consumed: 14 },
            { fruit: 'Bananas', yield: 9, consumed: 9 }   
        ];
    });

Knockout

HTML

JavaScript

<div data-bind="dxPieChart: {
    dataSource: fruits,
    commonSeriesSettings: {
        argumentField: 'fruit'
    },
    series: [
        { valueField: 'yield' },
        { valueField: 'consumed' }
    ]
}"></div>

var viewModel = {
    fruits: [
        { fruit: 'Oranges', yield: 10, consumed: 7 },
        { fruit: 'Apples', yield: 15, consumed: 14 },
        { fruit: 'Bananas', yield: 9, consumed: 9 }
    ]
};
ko.applyBindings(viewModel);

@(Html.DevExtreme().PieChart()
    .ID("pieChart")
    .DataSource(Fruits)
    .CommonSeriesSettings(c => c

    .Series(series => {

    End Sub) _
    .Series(Sub(series)
        series.Add().ValueField("yield")
        series.Add().ValueField("consumed")
    End Sub)

Note that DevExtreme widgets require you to link the jQuery library to your application. If you use the Knockout or AngularJS approach, the Knockout or AngularJS library is also required. For detailed information on linking these libraries to your project, refer to the topics in the Installation section.
