I don't have time to do this right now, but I will accept patches.

In which form do you want to have histograms? Are you interested in histogram with automatic categories, supporting several strategies for this?

While I would be interested by this, I am not sure how it would fit in gsl-ocaml.

@michipili Well, I don't use histograms so I wouldn't even know what users might be happy with. If the OCaml-API solves your problem and reasonably reflects the API of the underlying GSL-library (i.e. reading the original GSL-documentation will give you a decent idea on how to use the OCaml-bindings), then it would seem like a good fit.

@michipili i was just thinking of providing (thin) bindings to the 2d hist functionality present in gsl, as found here https://www.gnu.org/software/gsl/manual/html_node/Histograms.html

Oh, my bad, this is for me an unexplored part of GSL! :)
