[haskell-gnuplot] histogram

[Michael Litchard]

Thank you for this request. It made me think about how I was going
about this project. My approach was to go from what I conceived to be
a simpler model, and then go to a more realistic data set later. In
attempting to write a gnuplot script I realized that the sketch I sent
you didn't really help at all. So, I've sent you what I think is a
minimal but realistic sample dataset, with a gnuplot script. I took
the script from the gnuplot tutorial. I tried to remove as much as I
could that I didn't think was important.
