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!
