[Solved] Doughtnut series

[Bartlomiej]

Hello!

I've set AngleRange for Doughnut series from 0 to 360.
Now, the first segment is not started from 12 hour.
Is it possible to change this behaviour?


Best regards,
Bartłomiej

Hello Bartlomiej,

Thank you for using our RadControls for Windows 8.

Yes, it is possible. The AngleRange constructor takes two arguments - the first is start angle and the second is sweep angle. As we have accepted that the 0 start angle is on 3 o'clock and it is moving clockwise, to achieve the desired result the DoughnutSeries.AngleRange should be:

new Telerik.Charting.AngleRange(270,360);

I hope this helps. Let me know if you need further assistance.

 

All the best,

Hello!

In my first post I have forgot to mention about one important fact.
I was trying to set angle range from 30,360 and the result was the same, but selection wasn't working well.
I've tried Your solution but the result is the same.

The bigger start angle is set the biggest part of doughnut series can't be selected.

I've attached a simple solution with my case and create a support ticket (http://www.telerik.com/account/support-tickets/view-ticket.aspx?threadid=687133).
In this scenario, the start angle is set to 30 and if You try to select numer 2 on series, clicking on the second half of the segment, nothing is happen.

Hello Bartlomiej,

Thank you for getting back to us.

Indeed I can confirm that this is a bug and I have logged it in our system. Unfortunately I cannot suggest a workaround for the time being besides not customizing the start angle value. I have also updated your Telerik points for your valuable feedback.

If you have any other questions do not hesitate to contact us again.
