If I want to make a
TRatioPlot of two
TEfficiency objects (I want to see how a
TEfficiency from two different runs compare to each other), is there an easy way to do this?
It seems like for each
TEfficiency object I would need to use
TEfficiency::CreateGraph() to get the
TGraphAsymmErrors object, then do some small routine to copy the information in each
TGraphAsymmErrors object to a
TH1 object, and then from the two resulting
TH1 objects make a
TRatioPlot. However, this should fail as “histograms with asymmetric errors are not supported” (as of 2002 at least).
Is there a known (and efficient) way to accomplish this?
