I'm working on creating a line plot from a histogram, as in the following:

{g, {binCounts}} = 
  Reap[Histogram[RandomVariate[NormalDistribution[0, 1], 100], 
         Function[{bins, counts}, Sow[counts]]]];

{g, ListLinePlot[binCounts]}

What I'd like to know is, how can I normalised this line so the area under the curve is 1? (So I can compare the shapes of these histograms independent of the number of counts)

  1. Use the "Probability" hspec in Histogram (check the docs)

  2. Use HistogramList to get the data (instead of a plot)

    {bins, heights} = HistogramList[rr, Automatic, "Probability"]
