[FEATURE] plot_ratio() to support Weighted histograms
andreypz opened this issue · comments
Describe the problem, if any, that your feature request is related to
I believe the current plot_ratio() method does not take into account weights of the histograms when calculating the errors.
Describe the feature you'd like
Propagate errors correctly into the ratio uncertainty, taking into account the weights
Describe alternatives, if any, you've considered
Using coffea.hist.plotratio instead
Hi, I just encountered this - can a warning at least be added to the documentation that says that weights will be ignored in the calculation of the ratio? It's not obvious at all that they are ignored and this could easily lead to / have already led to incorrect conclusions/analyses.
