Re: [ROOT] gStyle in sub-pads?

Hi Rene,

please find attached the simplest example with which I can reproduce the problem
(I did not send the 1d-histogram since I don't think it is the origin of the
problem) and the resulting ps. 

I'm using root 3.05/07 for gcc 2.95.2 on RedHat Linux 7.2.

In fact, the problem is not related specifically to subpads, but to a subtle (at
least for me) interplay between c1.Clear() and gStyle.

In this example, of course, I could remove the c1.Clear() statement, then it
works. But if I want to use subpads, I need to do a c1.Clear() at some point,
which is why I discovered the problem when using subpads and thought it was
related to these.

Thanks in advance.
