I would like to have a shaded error band around my TGraph instead of the error bars. So I used the option “4A*” for drawing. This works fine except for the region between the last but one and the last point. There the interpolation seems to overdo things. I have attached a trivial example showing the effect.
So my question is how to avoid this feature…
Thanx for suggestions,
