Hi Rene,
it would be really nice if TGraph would have similar behaviour as TH1 for
things concerning drawing etc.
For hists I can use TH1::SetOption which then can (interactively) be
overwritten by SetDrawOption, but I (and I guess Peter) miss this feature
for TGraph.
Couldn't it be added? Perhaps using internally fHistogram->SetOption()
(in case there are no 'overlaps' between graph and hist drawing options)?
