(Feature to Potentially Upstream) extending org-plot.el

[Timothy]

Good news! This is the last of my "things I want to contact the mailing list about" backlog 😛

So, I recently wanted to be able to create a radar chart in org, using #+PLOT without a 500 character #+PLOT  line.

I started with advice-override, but quickly realised it would be better just to switch out org-plot.el with a modified version, which can be found here: https://github.com/tecosaur/emacs-config/blob/master/lisp/org-plot.el

As this currently stands, with the below table and plot line I can produce this plot https://media.githubusercontent.com/media/tecosaur/emacs-config/master/misc/document-format-comparison.png.

#+PLOT: transpose:yes type:radar min:0 max:4 file:"misc/document-format-comparison.png"

The colours are a doom-specific bit, because I draw them from the current doom theme. I figure this could just be replaced with a general purpose  entry point into the plot generation script where the user can add a 'custom preamble' function.

I'm also interested in refactoring the type:XXX bit so that it's more general, less hardcoded. I don't know what may be involved, but I'm thinking something similar to org export when you can define a new export function could be nice (hough I imagine that example is far more complicated than this would be).

I'm hoping that someone may be interested enough to provide feedback, and idealy help me extend org-plot in this manner, with the goal of having this functionality upstreamed (assuming interest in doing so).

Please let me know!

All the best,

tecosaur
