Hello,
I cannot figure how to get nice labels on X axis on the plots
generated by the attached macro.
If I set Ndiv to 1 or -1 I get a single major tickmark at 100,
a single tickmark at 500, and label at 500 and 1000.
Any other value produces the same number of major and minor tickmarks
and overlapping labels. I have been using ROOT 2.21/08.
Regards,
Michal Lijowski
