The histogram function supports a weights option, but most others (e.g.,
percentile) do not.
For my problem, I have a trace of the amounts of time (floating point) that
my machine under test is in each of N states. I'd like to produce
histograms, kde, maybe nice pics with seaborn.
I can use weights option to histogram, but cannot do any fancier ops,
because they don't accept a weights= input. For that matter, it would even
perhaps be nicer if they accepted a histogram input directly.
I looked at seaborn distplot, but it doesn't accept weights and doesn't
accept a histogram. I thought maybe I could modify it, but it uses
functions like percentile, which also doesn't accept either.
