This is possible but not easy. Have a look at the following code:

Private Sub Form_Load()
Dim s As String
TeeCommander1.Chart = TChart1
With TChart1
.Axis.Left.AxisPen.Visible = False
End With
End Sub


Private Sub TChart1_OnAfterDraw()
Dim Height
With TChart1
Height = .Axis.Bottom.Position - .Axis.Top.Position
Height = Height / 2

.Canvas.Rectangle .Canvas.ChartXCenter - Height, .Axis.Top.Position,
..Canvas.ChartXCenter + Height, .Axis.Bottom.Position
End With
End Sub

This code draws a rectangle around the Gauge series and should provide all
the information you need to use ICanvas.Line (see help for details) to draw
a series of short lines describing an arc with ICanvas.Pen(s) of different
colours.
