I have a set of
(x,y) points that are part of a distribution, so I want to make a histogram. The binning is variable but I don’t know how it got created.
What I have is the bin center and the bin content.
Is there a way to read this ascii file and make a histogram out of the points?
It looks like an easy thing to do, but I can’t get my head around it!
I tried in the past (Create histogram with a varying binning knowing BinCenter) but with no success.
TGraph wouldn’t work, because conceptually it is a distribution and also I would like to use
TH1 functions down the road.
That’s how my data points look like:
