Hello Aewin ,
Currently these Chart types are not supported with ASP.NET AJAX. However it is in our development plans to release Radar Chart and Polar Chart for Silverlight. Hopefully you will be able to download them with our upcomming Q3 2011 release. You may integrate them as any other Silverlight control in your asp.net ajax website as shown in our
Integration demo.
Best wishes,
Evgenia
the Telerik team
