Angular PieChart API
The PieChart is a widget that visualizes data as a circle divided into sectors that each represents a portion of the whole.
DevExtreme widgets are integrated with many popular libraries and frameworks. See the Installation section (for JavaScript libraries) or the Prerequisites and Installation section (for ASP.NET MVC framework) to find details on setting up DevExtreme with a particular library or framework.
The following code shows how to create the PieChart widget using every supported library and framework. For more details on working with widgets in these libraries and frameworks, see the Widget Basics topic for jQuery, Angular, AngularJS, Knockout or ASP.NET MVC.
jQuery
var fruits = [ { fruit: "Oranges", yield: 10, consumed: 7 }, { fruit: "Apples", yield: 15, consumed: 14 }, { fruit: "Bananas", yield: 9, consumed: 9 } ]; $(function() { $("#pieChart").dxPieChart({ dataSource: fruits, commonSeriesSettings: { argumentField: "fruit" }, series: [ { valueField: "yield" }, { valueField: "consumed" } ] }); });
<div id="pieChart"></div>
Angular
<dx-pie-chart [dataSource]="fruits"> <dxo-common-series-settings argumentField="fruit"></dxo-common-series-settings> <dxi-series valueField="yield"></dxi-series> <dxi-series valueField="consumed"></dxi-series> </dx-pie-chart>
import { DxPieChartModule } from 'devextreme-angular'; // ... export class AppComponent { fruits = [ { fruit: "Oranges", yield: 10, consumed: 7 }, { fruit: "Apples", yield: 15, consumed: 14 }, { fruit: "Bananas", yield: 9, consumed: 9 } ]; } @NgModule({ imports: [ // ... DxPieChartModule ], // ... })
AngularJS
<div ng-controller="DemoController"> <div dx-pie-chart="{ dataSource: fruits, commonSeriesSettings: { argumentField: 'fruit' }, series: [ { valueField: 'yield' }, { valueField: 'consumed' } ] }"></div> </div>
angular.module('DemoApp', ['dx']) .controller("DemoController", function ($scope) { $scope.fruits = [ { fruit: "Oranges", yield: 10, consumed: 7 }, { fruit: "Apples", yield: 15, consumed: 14 }, { fruit: "Bananas", yield: 9, consumed: 9 } ]; });
Knockout
<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);
ASP.NET MVC Controls
@(Html.DevExtreme().PieChart() .ID("pieChart") .DataSource(new[] { new { Fruit = "Oranges", Yield = 10, Consumed = 7 }, new { Fruit = "Apples", Yield = 15, Consumed = 14 }, new { Fruit = "Bananas", Yield = 9, Consumed = 9 } }) .CommonSeriesSettings(c => c .ArgumentField("Fruit") ) .Series(series => { series.Add().ValueField("Yield"); series.Add().ValueField("Consumed"); }) )
@(Html.DevExtreme().PieChart() _ .ID("pieChart") _ .DataSource({ New With { .Fruit = "Oranges", .Yield = 10, .Consumed = 7 }, New With { .Fruit = "Apples", .Yield = 15, .Consumed = 14 }, New With { .Fruit = "Bananas", .Yield = 9, .Consumed = 9 } }) _ .CommonSeriesSettings(Sub(c) c.ArgumentField("Fruit") End Sub) _ .Series(Sub(series) series.Add().ValueField("Yield") series.Add().ValueField("Consumed") End Sub)
