DevExtreme React - Create and Configure a Widget

Make sure you linked all the required resources before creating a widget:

For operating with AngularJS, DevExtreme includes an AngularJS module registered under the name "dx". Add it to the list of dependencies for your application module.

JavaScript
angular.module('myApp', [ 'dx' ]);

The "dx" module contains directives that you use to create any DevExtreme widget. For instance, the dx-button directive creates a Button widget, dx-range-slider creates a RangeSlider, etc. Note that all DevExtreme directives satisfy the AngularJS normalization rules: dx-widget-name.

Any DevExtreme directive should be associated with a <div> HTML element, which plays the role of a container for the widget. For example, the following code creates a Chart widget in a <div> container.

HTML
<div dx-chart=""></div>

To configure a widget, pass an object to the widget directive. Note that the properties of this object mirror the options of the widget.

HTML
<div dx-chart="{ 
    dataSource: [
        { fruit: 'Oranges', total: 10 },
        { fruit: 'Apples', total: 15 },
        { fruit: 'Bananas', total: 9 }
    ],
    series: { argumentField: 'fruit', valueField: 'total' }
 }"></div>

You can initialize widget options with the value of a scope property. For example, the following code declares the fruitsData property within the scope of a controller. The dataSource option of a dxChart is initialized with the value of this property.

JavaScript
function Controller ($scope) {
    $scope.fruitsData = [
        { fruit: 'Oranges', total: 10 },
        { fruit: 'Apples', total: 15 },
        { fruit: 'Bananas', total: 9 }
    ];
}
HTML
<div ng-controller="Controller">
    <div dx-chart="{
        dataSource: fruitsData,
        series: { argumentField: 'fruit', valueField: 'total' }
    }"></div>
</div>
NOTE
Initializing widget options in this manner does not mean that the widget option will be changed once its scope property is changed. If you are looking for this kind of data binding, refer to the Change Options topic.

As an alternative, you can declare the whole object of widget options in the scope and pass it to the widget directive.

JavaScript
function Controller($scope) {
    $scope.chartOptions = {
        dataSource: [
            { fruit: 'Oranges', total: 10 },
            { fruit: 'Apples', total: 15 },
            { fruit: 'Bananas', total: 9 }
        ],
        series: { argumentField: 'fruit', valueField: 'total' }
    };
}
HTML
<div ng-controller="Controller">
    <div dx-chart="chartOptions"></div>
</div>
