Funnel

The Funnel is a widget that visualizes a value at different stages. It helps assess value changes throughout these stages and identify potential issues. The Funnel widget conveys information using different interactive elements (tooltips, labels, legend) and enables you to create not only a funnel, but also a pyramid chart.

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 Funnel 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.
