Hello,
I am trying to find a way to average multiple (~40) histograms and display error bars. Are there any convenient ways of doing this? Thanks.

Simply enable error calculation
h[i]->Sumw2()
before filling histos
and then add them up in a loop
h[0] = h[0] + h[i]; for i=1, i<N
and scale by
h[0]->Scale(1.0/N), where N is number of histos.
