It might be nice to be able to overlay differently named histograms from different files.
In my imagination, we could specify targets like:
"fileA.root:dirA/hist0" "fileA.root:dirA/hist1" "fileB.root:dirA/hist1", etc...
A combination of the current "filenames" and "targets" lists. Perhaps targets could be a list of tuples:
targets = [("fileA.root","dirA/hist0"), ("fileA.root","dirA/hist1"),...]
My reason for this:
I have a file of histograms that comes from MC, it has both GEN and RECO level plots. Then I have another file of histograms which contain "unfolded" RECO level plots.
I'd like to overlay those 3 things, but how?
I guess one would have to split the first file into two madgraph_gen.root madgraph_rec.root ?
