Draw both in the same diagram? (histogram->Draw("SAME") iirc).
Draw a two-dimensional plot (probably not in the object browser)?

Root programming

It's not super easy to overlay two histograms on the same canvas in root using the root browser.

It's easiest to just use the command prompt or write a script to be executed by root. ROOT is essentially just a collection of C++ libraries, so there really isn't 'root programming' its just C++. One of the previous posters already gave the basic commands for that. I can give a more explicit example if you need it.
