I have some graphs with names big enough to reach thee top of the graph, and
there is then an overlap of the title of the graph on the term 10x-N, what prevents
from reading the value of N.
I attach such a graph to make my explanations clearer.
Is there a way to shift this title vertically not to have this overlap ?
I tried with TH2F->setTitleOffset() but it has no effect on this title.
Thanks for your help,
