In my WPF code, I'm calling

var hitElement = chartControl.HitTest(mouseEvent.Location.X, mouseEvent.Location.Y);

inside a mouse click handler, and I'm getting a DataPoint hit back correctly. This is working well.

When I click on a data point in a stock series that has OHLC data displayed as a bar or stick, will I be able, through hit testing, have any way of knowing whether the Open, Close, High or Low portion of that data point was clicked?

  Hi,

No unfortunately this information is not available in the hit test result. You can however perform a view to scale transformation:

NChart chart = (NChart)nChartControl1.Charts[0];
NViewToScale2DTransformation view2Scale = new NViewToScale2DTransformation(chart, (int)StandardAxis.PrimaryX, (int)StandardAxis.PrimaryY);

NVector2DD scalePoint = new NVector2DD();
view2Scale.Transform(new NPointF(e.X, e.Y), ref scalePoint);

and determine how the point is positioned relative to the OHLC range.

We hope this helps - let us know if you have any questions.
