[Solved] StartAngle for Silverlight Pie & Doughnuts

[B@ett]

How does one go about modifying the 'Start Angle' of pie & doughnut charts?
I have spent a significant amount of time exploring my options to no avail. While there is an example for how to do this in Pie Chart Start Angle for ajax, I have been unable to locate any such solution for silverlight, specifically from the code behind.

e.g. PieSeriesDefinition Pie = new ...
Pie.StartAngle?

Any Suggestions?

Thanks in advance for your help!

Hi B@ett,

You can achieve the desired effect like this (positive value shifts the starting point counter-clockwise, negative value shifts the starting point clockwise):

RadChart1.DefaultSeriesDefinition = new PieSeriesDefinition() { StartAngle = 90 };
RadChart1.ItemsSource = new int[] { 1, 2, 3 };

The same approach applies for DoughnutSeriesDefinition as well.

Thanks Freddie,
I have tried to incorporate that already and unfortunately I get a compiling error.  Am I missing a reference?
Thanks,

Hello B@ett,

The StartAngle property was introduced with the latest official version of the control (Q3 2010 - v.2010.3.1110) -- could you confirm that the version number of the referenced assemblies in your application is equal to this version?

We have attached a sample application for your reference.
