This may be a silly question, but is there a way set the error bars in the horizontal direction of a TProfile to the error on the mean of the x-values in this bin? Currently it sets it to half the bin width. Could the points also be set to the average value of x in this bin as opposed to the centre?
I realise this is easy with TGraphErrors but I am using a TH2D::ProfileX() to generate the profile. How do I convert between the two?
Thanks,
Ben
