WebJan 13, 2016 · I am trying to create a histogram with variable bin width, but I believe that the constructor for TH1F states that the widths must be binwidth+1. Here are my lower bin bounds: 0.0, 0.4, 0.58, 0.90, 1.08, 1.50, 2.20. Is it possible for me to plot these variable bins? My input so far is: root [0] Float_t Lower [7]; root [1] Lower [0]=0.0; Web• $ROOTSYS/etc/system.rootrc //global ROOT directory Ifmorethanone.rootrc ﬁleisinthesearchpathsabove,theoptionsaremerged,withprecedencelocal,user, global. … WebNow, if you want to use the histogram to get a continuous density, one that integrates to one, the you need to take into account the bin width. You can do that by defining p ( x) = ∑ i = 1 10 p i Δ ⋅ I i. I i is a function that is one on the i th bin and zero otherwise. Δ is the bin width which would be Δ = 1 in our example. density of aluminum pounds per cubic inch
