[ROOT] feature-wish enhanced set(get)minimum()-AI :-)

hi!

The default minimum is zero for all positively filled histograms, so when a 
histogram is filled with very high values, it is very much zoomed out. 

Q1: Is there a reason not to put the displayed minimum by default to 
GetMinimum()/1.1 or something similar?

But now, whereas this normally can be solved easily by doing
h->SetMinimum(h->GetMinimum()/1.1)
this is not possible, when some of the bins have never been filled and 
therefore the 'official' histogram's Minimum is still zero.

So I always have to include some dummies to keep track of the actual minimum 
of measured values to adjust the histogram later.

Question 2 is, if this is a situation met by many people, could maybe a flag 
be introduced for ignoring empty bins for the getminimum()-function or maybe 
only for the setminimum()-case. I wouldn't know, how this could be solved 
most efficiently, just feel like this could be the case for many people.

What do people think?

Cheers, and happy weekends everybody!
Michael
