Hi Hannes,

it seems that the histograms you want to compare have different binnings.
Your reference data file has 18 bins while the MC histo has 19 bins.
Maybe you want to check that the datafile used when plotting is identical
to the one read in when rivet is running (RIVET_REF_PATH).
So in that sense, the error message you get it correct.
