Angular Bullet API

The Bullet widget is useful when you need to compare a single measure to a target value. The widget comprises a horizontal bar indicating the measure and a vertical line indicating the target value.

import { DxBulletModule } from "devextreme-angular"

Type: DxBulletTypes.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 Bullet 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.
