hi, is it really true that i have to use SetMinimum(0) for each of my histos in order to keep the y-axis at zero? no other way? am i the only person that complains? for me, the 'old' way is much more 'natural'! just a simple example: you fill a spectrum randomly (uniform). what you then teach your students is that - as you keep on filling - the relative error gets smaller and the distribution finally looks flat. what you now see is that the absolute error increases, which is nice to know, but does not help. btw, we have at least 10^5 histos distributed over about 200 macros/programs in our analysis code. so again the question: can i set the minimum in my .rootrc/.rootlogon/...? cheers, martin On Wed, 1 Sep 2004, Olivier Couet wrote: > > Hi, > > Yes the behavior has changed.
