Hello, I need to display thick color vertical line in 3D surface graph at coordinates X = 0, Z(depth) = 5 (at the middle of the depth axis). Do you know how to achieve this? Any idea or way how to display it will be wellcomed. I'm using Teechart v7 activeX. Thanx for reply.

Hi zizou5,

You can custom draw this on TeeChart's canvas like this:

Code: Select all

Private Sub Form_Load()
    TeeCommander1.Chart = TChart1
    
    TChart1.AddSeries scSurface
    
    For X = 0 To 10
        For Z = 0 To 10
            TChart1.Series(0).asSurface.AddXYZ X, Rnd, Z, "", clTeeColor
        Next
    Next
    
    TChart1.Axis.Depth.Visible = True
End Sub

Private Sub TChart1_OnAfterDraw()
    X0 = TChart1.Axis.Bottom.CalcXPosValue(0)
    X1 = X0
    Y0 = TChart1.Axis.Left.IStartPos
    Y1 = TChart1.Axis.Left.IEndPos
    Z = TChart1.Axis.Depth.CalcXPosValue(5)
    
    With TChart1.Canvas
        .Pen.Width = 5
        .Pen.Color = vbBlack
        .LineWithZ X0, Y0, X1, Y1, Z
    End With
End Sub

Cool, that is exactly what I've needed. Could I also draw text into 3D space with specific coordinates?

Hi zizou5,

Yes, use TextOut3D method.
