[Rivet] Proposals for make-plots

Thanks, two good points. So if I come up with a more stringent test 
telling whether it's logarithmic in x then I'll try to find the right 
place in compare-histos to put it into.

Have you tested it? I actually found it to be working quite nicely. I 
have prepared the following for testing:

http://fsiegert.web.cern.ch/fsiegert/tmp/density/72/
http://fsiegert.web.cern.ch/fsiegert/tmp/density/85/
http://fsiegert.web.cern.ch/fsiegert/tmp/density/100/

If you still think 72 is too small, what about a compromise at 85? That 
way I could at least have two plots on a half-width window of a 1680 
pixel display. ;)

Cheers,
