I know that I can put labels on the X axis, but I don't want to have an 
X axis... In the end I would like to draw the graph from top to bottom 
(instead left to right) and put labels on the left side, again without 
any axis, because it doesn't make much sense. This rotation does not 
concern me right now, but I would like to zoom the graph. Can you point 
me to the place in the ROOT source where the association is made 
between the TFrame and the pad coordinate system when drawing a 
standard histogram? Or is this mechanism in principle not usable 
without a TFrame?
