Hi rooters,
I am a beginner, I’m running v5.30 of windows7.
I have a problem with an histogram (TH2F).
I’m trying to put two graphs on the same plot, with a second Y axis (on the right side).
I am trying following the online tutorials but I can’t repeat it on my script.
can you help me?
You can find attached the script
thanks
Cris
PS: I.m Sorry 
, I’ve already posted my topic directly to roottalk@root.cern.ch,
now I’ve joined the forum and I’m posting it again …here, only too to be sure.
multyplot_00.c (8.47 KB)
See $ROOTSYS/tutorials/hist/twoscales.C
and option X+ and Y+ here : root.cern.ch/root/html/THistPainter.html
I am a beginner too. I tried to run your multyplot_00.c but I get segmentation faults:

What can I do?
Besides that, I would be able to add more that two axes to a series of traces in a single graph:
time VS many traces
This thing is possible with python + matplotlib
Is it possible with ROOT?
I used: ROOT ROOT 6.28/08
Thanks to all
