Continuing the discussion from [[ANN] First release of OCaml bindings to the Polars dataframe library](https://discuss.ocaml.org/t/ann-first-release-of-ocaml-bindings-to-the-polars-dataframe-library/13382/3): > [@\[ANN\] First release of OCaml bindings to the Polars dataframe library](https://discuss.ocaml.org/t/ann-first-release-of-ocaml-bindings-to-the-polars-dataframe-library/13382/3): > > > Also, what would you recommend for interactive plotting? > > I haven’t personally tried it yet, but I think @laurent 's [GitHub - LaurentMazare/ocaml-matplotlib: Plotting for ocaml based on matplotlib.pyplot](https://github.com/LaurentMazare/ocaml-matplotlib) library should work with ocaml-jupyter so would probably be worth trying out. There’s also [sanette/oplot: Mathematical plotting library for ocaml](https://github.com/sanette/oplot). If you’re interested, I might polish and release (or upstream to PrintBox) [a tiny utility](https://github.com/lukstafi/ocannl/blob/master/lib/PrintBox_utils.ml) for plotting in text (useful for expect tests or CLI interfaces). ---

```bash opam search plot ``` returns a long list; some are libraries to help with ploting. ---

Wow, this looks quite useful! I think I’d definitely use it my libraries it if it were available on opam! ---

Other library: [ocaml-gr](https://github.com/mseri/ocaml-gr) → It is a binding of a C-library which aims to be fast, and it is used in the Julia comunity as a backend of several more highlevel libraries. [ocaml-vega-lite](https://github.com/apatil/ocaml-vega-lite) → I guess it produces json documents to be plotted with vega-lite I’m not an expert but in OCaml there are a bindings to Cairo library, which is widely used to build plotting libraries on top of it. Maybe something like [ocaml-gg](https://erratique.ch/software/gg) would be an alternative. ---

For those who want to try something new, I’ve found the following procedure to work: ```sh opan pin gg --dev-repo opam pin vg --dev-repo opam pin https://github.com/dbuenzli/vz.git ``` then patch up ```diff --- .opam/5.1.0/lib/vz/META.orig 2023-11-09 19:17:31.897443541 +0100 +++ .opam/5.1.0/lib/vz/META 2023-11-09 19:19:34.731868303 +0100 @@ -34,7 +34,7 @@ description = "Quick cartesian plots of datasets" version = "0.0.0-35-g2667067" directory = "plot" - requires = "gg vg vz evidence" + requires = "gg vg vz vz.evidence" archive(byte) = "vz_plot.cma" archive(native) = "vz_plot.cmxa" plugin(byte) = "vz_plot.cma" @@ -57,7 +57,7 @@ description = "Evidence sample data" version = "0.0.0-35-g2667067" directory = "samples" - requires = "evidence" + requires = "vz.evidence" archive(byte) = "evidence_samples.cma" archive(native) = "evidence_samples.cmxa" plugin(byte) = "evidence_samples.cma" ``` and hunt for examples and docs at [Vz / Erratique](https://erratique.ch/software/vz).

This is available now as a PrintBox extension package [printbox-ext-plot](https://ocaml.org/p/printbox-ext-plot/latest): [printbox/src/printbox-ext-plot page with examples](https://github.com/c-cube/printbox/tree/main/src/printbox-ext-plot).
