I’ve just noticed something peculiar when drawing 1D histograms.
TH1F h(“h”,"",3, 0,3)
I get the histogram drawn with a y range going from a bit less than 110 to a bit more than 115. It is a bit misleading for me, since you do not get an idea of the statistics involved without looking at the scale… What I would like is :
- when the values in all bins are positive, the y range starts at 0.
- when at leat one value is negative, the min y is determined automatically so that all values are displayed.
Is there an option to get this behaviour by default ? I would prefer not to have to pass an option to TH1::Draw, nor call TAxis::SetRangeUser
I’m using root 4.04/02f
