Hi Rene,

thanks for introducing the fix. I do not know if you have already introduced
a fix for for kClipFrame in default TGraph() constructor. It was missing in
2.23/12 version. Is it there in the latest version?

Regards,
Anton

Hi Anton,
Thanks for reporting with clipping problem with the option "bar"
I have introduced the fix in my development version.
Note that a TGraph object is always clipped at the frame boundary.
You do not need to set the kClipFrame bit.
