I would like to access the y axes in a TRatio plot for 2 reasons :
- customize the range
ratio_20_30->GetUpYaxis()->SetRangeUser(0., 60.); is not working
- taking as example https://root.cern.ch/doc/v618/canvas2_8C.html i am trying to stitch together 5 ratio plots but the labels on y make them really inequal …
So, can somebody point me to the correct ways to achieve my goals?
Thanks a lot!!
