Clicked(X,Y) and ColorGrid series

[Gareth]

Hi

I am trying to use the Clicked(X,Y) function with a ColorGrid series with its
IrregularGrid property set to false. It always seems to return -1, except
for a small region just above the X axis, where it seems to work Ok. Is there
an issue with this function and Irregular ColorGrids?

I am using C++Builder 6 with TChart V7.07.

example code:

Code: Select all

void __fastcall TMDIChild::Chart1MouseMove(TObject *Sender,
      TShiftState Shift, int X, int Y)
{
    if(ColorGrid->Active)
    {
        int i = ColorGrid->Clicked(X,Y);
        if(i!=-1)
        {
            double Val =  ColorGrid->YValue[i];
            Chart1->Title->Text->Strings[0] = FloatToStr(Val);
        }
    }
}

Thanks

Hi Gareth,

does the example included into the Demo Features project, under :
All Features -> Welcome ! -> Chart Styles -> Statistical -> Color Grid -> Mouse Hits, shows what you're looking for ?

Hi

Sorry, what I meant to say was that the Clicked(X,Y) method does not seem to work
when the IrregularGrid property is set to true.

The example you mentioned does indeed work, but only if the IrregularGrid property is set to false, set it to true, then it no longer works.

Thanks and sorry for the confusion
