Dear Rooters,


I have a ntuple file which contains variables such as Evis, Pt, Pl, and
etc.. I apply cuts in each of this variables and then draw. I have a
little problem on how to change the range of the x-axis on the resulting
histogram. How can i do it? Also, on the y-axis, i've noticed that the
scaling is arbitrary. Is there a way on how to change the scale such that
the range is of the order of let say, 10, 10^2, 10^3, and so on.
