JavaScript/jQuery 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 Bullet from "devextreme/viz/bullet"

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.
