Re: 2 plots in the same canvas

I have a Root macro, HistoRoot.C, that implements a GUI interface to generating histograms and X-Y plots from TNtuple-s. It reads any number of TFile-s and can plot expressions using variables from any TNtuple found in any of them; it can also convert an ASCII file into a TNtuple. It implements sliders to impose interactive cuts on the plots. And yes, it can combine multiple plots onto a single canvas.

It is available as part of my G4beamline release, and will soon be released as a standalone program. If you want a pre-release copy just ask. My users and I have found it to be quite useful, and much easier to use than TBrowser or C++ code. It works on Root 5.12 and 5.14, and probably other versions.
