As part of our testing, we want to simulate clicking on a pie chart segment, using x,y pixel co-ordinates. What is the simplest way to achieve this?

Thanks

Hi Kevin,

You can perform hit test using the HitTest method:

NHitTestResult result = nChartControl1.HitTest(x, y);

if (result.ChartElement == ChartElement.DataPoint)
{
   // result.Series contains the series of the data point
   // result.DataPointIndex contains the data point index
}

Is this the functionality you're looking for?

No, I'm already doing that. The tester wants to simulate clicking on a pie segment to check my hit test code, so the tester needs the reverse information. He needs to know the x and y pixel coordinates to input into his test, whcih corresopond to clicking on a a pie chart segment.

Thanks

Hi Kevin,

That will be difficult - in the sense that you'll have to replicate the whole rendering code of the pie 2D/3D plus you'll need to take into account the non overlapping labels if you use them... In general you need to use a simpler approach - like as if the user has clicked pie1 or pie2 (skipping the hit test from mouse).

Sorry, I don't understand why it's so difficult. All I want is an (x,y) coordinate which lies within a given pie segment. I don't care where the point is within the segment. Am I missing something?
