Sparkline

The Sparkline widget is a compact chart that contains only one series. Owing to their size, sparklines occupy very little space and can be easily collected in a table or embedded straight in text.

Included in: dx.viz.js, dx.viz-web.js, dx.all.js
Module: viz/sparkline
Export: default
Sparkline interactive configuration
Copy Code
Copy to Codepen
$("#sparkline").dxSparkline({
});

                    

You can create the widget using one of the following approaches.

Note that DevExtreme widgets require you to link the jQuery library to your application. If you use the Knockout or AngularJS approach, the Knockout or AngularJS library is also required. For detailed information on linking these libraries to your project, refer to the topics in the Installation section.
