[ROOT] Full controle over axis

Dear Rooters,

I wonder how it is possible to decide the range of 
the x and y axis around a histogram. 

For example if the highest bin in one histogram is
590 then the range of the y axis goes up to around
600 automatically. I wanted to change this to 1000 :

  Axis_t ymin = 0.0;	
  Axis_t ymax = 1000.0;
  hist->GetYaxis()->SetRangeUser(ymin, ymax);
  hist->Draw();  

But nothing happened (not even an error message).
So the y axis stayed as it was before. How can I
get full controle of the view range of the axis
of an histogram? I've also tried with SetLimits 
with the same result; nothing happened.

The reason why I want to controle the axis limits
is because I want to show this histogram as a 
comparison with another histogram, and that will
work better if the two histograms are plotted 
in axis with the same range. 

Thank you
