Look the image below to understand : the bottomAxis is "cut" when I'm using a gradient in the TeeSeriesBandTool. For this example, I have changed a bit the axis position to be able to see it.

Can you please check this problem again with v8.02 ? It really seems to be a problem in TeeChart, but I couldn't locate exactly where the axes are cut at the edge of the chart.
I'm using only customAxes (except bottom), maybe it can help you.
P.S. :
Just a tip :
I remember that I had reported a bug about TeeSeriesBandTool :

Maybe my current problem is linked to the modification you made for this problem.
