Hello again, have a question about setting the size of graph titles on 
graphs that are generated by a macro. By title i mean the box in upper 
left that is set by TCanvas::SetTitle(), not the titles of the axes. I 
have tried the following:

gStyle->SetTitleFontSize(0.1); this doesn't seem to ever work, even after 
gROOT->ForceStyle

TPaveText *title = (TPaveText*)plotcanvaskey->GetPrimitive("title");
title->SetTextSize(0.08);
plotcanvaskey->Modified();

The previous works for c1 autogenerated canvases but not ones i make :(

Just plotcanvaskey->GetPrimitive("title") returns a null pointer. Doing a 
plotcanvaskey->GetTitle(), returns a string of the title text, but not the 
pointer to the title object, unlike plot->GetXaxis().

Am i missing something, or confusing graph title with axis title? I am 
using root-3.05.02 on RH-7.2 linux with gcc-2.96 compiler.

Regards,

Tohru O.
