[Solved] Doughnut/Pie and start angle

[Lars]

I am looking for a way to set the start angle for a doughnut or pie series from XAML.

I see that there is an AngleRange, but I'm not sure how to use this. Again, my requirement is for a XAML only solution.

Thanks!

Hi Lars,

Thank you for your interest.

As the AngleRange property of the RadPieChart is of type AngleRange(startAngle,sweepAngle) structure, it cannot be set in XAML(WinRT restrictions). So, you can set it in code like this:

this.chart.Series[0].AngleRange = new AngleRange(90, 180);

The other option you have is to bind the series to a ViewModel that has a property of type AngleRange.

The startAngle is the start angle from which the arc starts(0 matches the (0,0) point) and the sweepAngle is the angle that defines the length of the Arc.

I hope this helps. Let me know if you have any other questions.

Thank you. I would like to ask Telerik to consider adding some simple dep properties that are XAML settable. In my opinion, this would improve the design time experience.
