Unfortunately polar charts will not be available until the end of 2010. We are aware of this feature's popularity in PITS and regard it with priority, however, it did not make it in for Q3 due in November. The reason for this is that our DataVisualization team gets a lot of internal requests for features needed in other telerik products.
We can provide further information at the end of November / early December (this is when our planning phase is complete) regarding whether this feature will be scheduled for development in Q1 2011.
We sincerely apologize for the inconvenience caused.
