Superimpose TEfficiencies

ROOT
1

Dear experts,

I am trying to superimpose 2 TEfficiencies but I can’t see how to do this. I would also like to draw them in 2 different colors.

Otherwise, if you can explain to me how to manually impose bayesian erros on TH1F, I would be glad.

Thanks a lot,
David

Accoding to the doc the TEfficiency Draw method seems to behave as the TGraph one.
So simply draw your first TEfficiency using option ‘A’ plus L or P art both and the 2nd TEfficiency without ‘A’ it should super-impose them.
