Hello Rene,

assume I have a graph drawn on top of a TH2 histogram (as we usually do in
ROOT to draw multiple graphs on the same picture). Assume I zoom a histogram
along X axis.  Now in my code I want to zoom the histogram along Y axis so 
that zoomed (along X) portion of graph fits Y histogram range. To do so I have 
to know Ymin and Ymax of my graph on the zoomed X. How can I get it? I have tried
TH2::GetMinimum() and TH2::GetMaximum() but they both return zero all the
time.

Regards,
Anton
