I guess if one would implement a standard option “*” or whatever of TGraph::Draw() (if no option given) some beginners would be very happy. Also drawing the Graph by TBrowser reading a root file would work properly. This is a piece of cake, is it?
The behavior to clear the pad and compute the scale automatically is only implemented for objects like TH1 and TF1. We cannot do that for the low level objects drawing lines and text, eg TLine, TText because there are in general many objects of these types in the same pad.
TGraph is somehow at an intermediate level. But we cannot change the default behavior for back compatibility.
