Hello,
I’m drawing solar system diagrams using the pgfplots module, but the polar
library seem to be broken. It looks like it is calling something with a
\begin{axis}... command. Here is the error message for a short document,
included below.

I’d love a fix or an idea for a work around. I’m using ConTeXt Suite (ver:
2020.12.15 10:10 MKIV fmt: 2020.12.16), but I’ve tried it with TeX Live 2020
and the MkIV included with LMTX. Both have the same issue.
Thanks!
Gavin
