[Rivet] Stack= options for *.plot files

[Hendrik Hoeth]

Hi David,

I think there is quite a bit of confusion going on. So instead of
answering your questions directly, I'll try to give some background
information about the tools.

rivet-mkhtml (which you are probably using) is nothing more than a
convenient front-end to compare-histos and make-plots. It will take one
or more Monte Carlo files as input, find the corresponding data files
(if applicable) and hands them to compare-histos.

compare-histos takes those files and creates one .dat file *per
observable* from them, which then holds the data and Monte Carlo numbers
for *that specific observable*. So in your case you'll have one file
with all your WJetCharge numbers, one with all the QuarkJetCharge
numbers, etc.

make-plots then generates a plot as .pdf and .png for each of those .dat
files.

Sooooo, having said that, it now should be clear that you cannot plot
multiple observables (like WJetCharge AND QuarkJetCharge) into the same
plot using rivet-mkhtml. But: make-plots is a generic histogram plotting
tool, and if you create your .dat files yourself (putting the numbers
for the different observables into one file), you can of course plot
whatever your like.

Now some comments on your questions:

Thus spake David Bjergaard (dbjergaard at gmail.com):

1) Stack takes the histogram identifiers as used in the .dat file. This
   will, by default, include the full file path to the .aida file if you
   use rivet-mkhtml. There is no simple way of using "Stack=" in a .plot
   file.

2) Wildcards don't work with options, just with IDs in the "# BEGIN ..."
   lines.

3) As mentioned above, you cannot mix observables with rivet-mkhtml.
   Thus your .plot file won't work the way to want.

A behaviour like "nostack" is the default in make-plots.

I've also attached an stacking example. Does this make things a bit
clearer?

Cheers,

    Hendrik
