Angular Chart API

The Chart is a widget that visualizes data from a local or remote storage using a great variety of series types along with different interactive elements, such as tooltips, crosshair pointer, legend, etc.

import { DxChartModule } from "devextreme-angular"
Type: DxChartTypes.default

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 Chart 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.
