Hello,
I need to superimpose two histograms with different scales in the same pad. There is an example twoscales.C in the tutorials which does this, but the problem there is that when I zoom the x-axis with the mouse the right red axis goes away. How do I modify the script in order to keep this axis in the same position even after zooming?
An idea which came to my mind is to use TCanvas::AddExec() and redraw the axis each time I make a zoom, but it seems there should be more elegant way to do it.
Thank you.
