Hi Norbert, I agree with your request. However this implies several changes in the TGraph class. Once we have terminated with our first development version 2.23, I want to start a reimplementation of the TGraph class. The new class will have (like in TH1) members fXaxis and fYaxis. This should solve your problem and give a behaviour similar to TH1.
