Hi Faizullah,

You can try doing something like this:

Code: Select all

Private Sub AddValue(X As Double, Y As Double)
    If ((X = 0) Or (Y = 0)) Then
        TChart1.Series(0).AddXY X, Y, "", clNone
    Else
        TChart1.Series(0).AddXY X, Y, "", clTeeColor
    End If
End Sub

Private Sub Form_Load()
    TChart1.AddSeries scLine
    
    AddValue -2, 6
    AddValue -1, 2
    AddValue 0, 3
    AddValue 1, 5
    AddValue 2, 0
    AddValue 3, 8
    AddValue 4, 4
    AddValue 5, 0
    AddValue 6, 2
End Sub

Hi

Thanks it works fine.

How we check the property of point e.g. At Run time We want to show

the point that is already marked as " clNone " or We want to assign "clNone" property to another point.

Thanks & Regards

Hi,

you can use the PointColor property :

TChart1.Series(0).PointColor(Index) = clNone
