[SOLVED] How to get XValue in OnClickBackground event ?

[Komar]

Hi,

I'm using Teechart pro 7.07 for C++ builder6.

I have a chart with a OnClickBackground event. In this event I would like to get the XValue of my click. The XValue must be the XValue of my bottom axis, at the place of my click, with my scale.

Do you know if it's a way to get that ?
Thanks...

Hi lp,

Yes, you can do something like this:

Code: Select all

void __fastcall TForm1::Chart1ClickBackground(TCustomChart *Sender,
	  TMouseButton Button, TShiftState Shift, int X, int Y)
{
	double XVal = Chart1->Axes->Bottom->CalcPosPoint(X);
	Chart1->Title->Text->Add(FloatToStr(XVal));
}

Hi Narcis,

Thanks for your answer. Your code has solve my problem. I didn't know the CalcPosPoint(X) function.
Thanks
