other backends? - Githubissues

allefeld commented 3 years ago

Does plotnine have an abstraction level that would make it (relatively) easy to implement backends besides matplotlib? I'm asking because I really like the gg logic, but would prefer interactive graphics like those provided by Plotly or Bokeh.

Plotnine does not have an abstraction level, nonetheless another backend is possible. How easy? It would depend on the package.

Theres also this 'matplotlib->d3' conversion library, which I presume should work with plotnine - I haven't tried it though.

@has2k1 Have you ever thought about adding a vega-lite backend like altair?

I find that altair renders plots multiple times faster than plotnine (e.g. 35s -> 7s in a big facet_grid plot I happen to be working on right now) — I'd guess this is because plotnine is generating a big png (~1900x1000px) whereas altair/vega are just generating js/dom for the browser to render. [nb: I just tried saving an .svg instead of .png to see if that was faster but it's not, it's actually a bit slower, 31s for png vs. 38s for svg.]
But I much prefer the ergonomics of plotnine/ggplot code over the corresponding altair code (e.g. time histograms have weird challenges in altair/vega), as well as the aesthetics of plotnine/ggplot plots over altair plots (e.g. facets strips in plotnine/ggplot are visually prominent whereas in altair they aren't prominent and get noised out by the repeated axis titles)
(Aside: the main thing I would miss from altair is the flexibility of combining arbitrary plots with vconcat/hconcat. I'd love to have that capability in plotnine, but that's a separate issue.)

I'd love to have the best of both worlds! plotnine + vega-lite = <3

Yes I have thought about vega-lite, but I do not have the bandwidth to take on javascript.

Are there any updates on this issue? I am trying to find workarounds on the internet but there aren't many to be found, and what can be found doesn't work or is too janky.
