Is fill gradient enabled on RadDiagram?

I downloaded the Q2 2015 version of Telerik asp.net controls and my question:

Is fill gradient enabled on RadDiagram control? 

I assume this feature is enabled because I see the next sample on Kendo Diagram and gradient is enabled:

Please tell me If gradient is enabled on RadDiagram asp.net control.

Thanks
