ocaml-matplotlib's Introduction

ocaml-matplotlib

Plotting for ocaml using matplotlib pyplot and object-orient apis.

Use in Jupyter notebooks

To use in an ocaml jupyter notebook, you can add the following in you jupyter init script, or in a notebook cell.

open Matplotlib;;
let plot () =
  let data = Mpl.plot_data `png in
  ignore (Jupyter_notebook.display ~base64:true "image/png" data);;

let () =
    Mpl.set_backend Agg;
    Mpl.style_use "ggplot"
;;

Using plot in the notebook then flushes the current picture and displays it (no need for a temporary file, everything is in memory).

how can i build this (trying to contribute)

I'd like to modify the code in the .opam lib folder and then rebuild and test to eventually contribute here.

in ~/.opam/4.13.1/lib/matplotlib
running "opam ins ." on unchanged code downloaded from opam gives the error quoted below.

I'm not sure if I have totally the wrong approach to building this (I don't know how to use dune...), or if there's some other problem. Is there a simple way to build the package and install it?

Thanks!

Showing a plot without blocking the process?

After Matplotlib.Mpl.show(), the program is blocked from interaction until the matplotlib window is closed. Is there a way to generate (multiple) plot windows and keep them open while continuing interaction with the ocaml process (not interaction with the plot itself)?

opam release?

Hi, I'm not sure how this works, but the version I have through opam isn't the most up to date -- in particular I'm looking for the legend functionality, which I see you've added after your initial publication to opam. Would it be possible to push the latest over to opam?
