Wrong bar index.

[blekdzhon]

Hello.

When I try to get bar index by

 ChartControl.GetSlotIndexByX(X)

sometimes I get wrong bar index. Sometimes it misses bar I'm not sure why.
I've also tried

ChartBars.GetBarIdxByX(ChartControl,X);

X coordinate I obtain from mouse click -

GetPosition(ChartControl).X

.
The issue occurs only on one PC.
On others PCs it works well.

Listed below is my code.

void OnLeftClick(object sender,MouseEventArgs mouse)
{
SplitFromCLick((int)mouse.GetPosition(ChartControl).X(float)mouse.GetPosition(ChartControl).Y);
}	
public void SplitFromCLick(int X, float Y)
{
 Print(String.Format("bar_index {0}",ChartControl.GetSlotIndexByX(X)));
}

Hello,

Thank you for the post.

To find specific Bars, you should be using GetBarIdxByX.

GetSlotIndexByX would return the area that can hold a bar which may or may not contain the bar in question.

Have you tried using the example from the first link and how it gets the mouse point? ChartControl.MouseDownPoint

If that does not aid in correcting the problem, could you provide an example as a .cs file that I could test to see the specific syntax and how it is used?

I look forward to being of further assistance.

Did you finally resolve this? I have the same issue on one PC, but not on the other

Hi. Yes I use the following function to obtain correct x coordinate.

ChartingExtensions.ConvertToHorizontalPixels(mouse.GetPosition(ChartPanel as IInputElement).X, ChartControl.PresentationSource);
