We don't have a built-in way to do that -- compare-histos will only
compare histograms with the same AIDA path (modulo a leading "/REF").

This is the sort of thing where we would benefit from having a
programmatic interface to histo manipulation... maybe we can find a
couple of days to hash something out sometime. A programmatic interface
to the plotting goodness in make-plots would be great, too.

In the meantime, you can do it by hand by cat'ing together the .dat
files, removing the extraneous PLOT section, and commenting out /
appending to the DrawOnly directive.

Hope that helps,
