In the documentation for THistPainter, the THn’s support bar-related drawing options including multiple histograms offset by some amount.
I would like to use this functionality to make something like Figure 4 here (Measurements of the production cross section of a $Z$ boson in association with high transverse momentum jets in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector)
where we have asymmetric errors drawn (hence the TGraph / TGraphAsymmErrors). How can this be done? Is the option to draw a TH1 with the regular binning, and then make TGraphs with expanded binning and draw them on top of the plot?
