TRatioPlot confidence band documentation


I am using a TRatioPlot to show the residuals of a fit on my histogram. I have some troubles understanding the confidence bands in yellow and green and I can not find any documentations on this. Do you have anything that could help ?


Maybe @couet can help here.

See ROOT: TRatioPlot Class Reference


Thank you for your answer but I meant what do they represent and how are they computed ?

Best regards,

You can trace it in the code here: ROOT: graf2d/gpad/src/TRatioPlot.cxx Source File
around line 987
