HTML5 Data Visualization

With this release, we've extended the capabilities of DevExtreme Complete with new HTML5 data visualization widgets, new charts types, improved end-user experiences and dramatically improved performance.


New Polar Chart

Polar Charts are a great way to display data whose values span cyclically repeating arguments. By using polar coordinates, you can display values related to each argument cycle as points - each displayed in a corresponding sector and having a radius proportional to the value itself. If you have multiple series, this widget allows end-users to compare values by viewing the resulting polygons.
