Setting X-Y Values and Coloring individual points in a point

John P. Francis · Post by **John P. Francis** » Thu Mar 29, 2007 12:12 am

I think I've asked this question before, but cannot find the answer on how to re-color a point in a point series and how to move the point to a new x-y value location.

Thanks

Hi John P. Francis,

You can try doing something like this:

Code: Select all

Private Sub Command1_Click()
    TChart1.Series(0).XValues.Value(5) = 3.5
    TChart1.Series(0).YValues.Value(5) = 7.5
    TChart1.Series(0).PointColor(5) = RGB(0, 255, 0)
End Sub

Private Sub Form_Load()
    TChart1.Series(0).XValues.Order = loNone
    TChart1.Series(0).ColorEachPoint = True
    
    For i = 0 To 10
        TChart1.Series(0).Add i, "", RGB(255, 0, 0)
    Next
End Sub

Also remember that for changing points values there's DragPoint tool as well.

m_Chart.Series( series_index ).GetXValues().SetValue( point_index, double_value);

There doesn't seem to be a function like:

m_Chart.Series( series_index ).GetPointColor().SetColor( RGB(0,255,0));

Hi John,

What about using this?

Code: Select all

	m_Chart.Series( series_index ).SetPointColor( point_index, RGB(0,255,0));
