Aditya,

Thanks for the quick fix! I will post a bug report on the pgfplots mailing 
list, including your helpful diagnosis of the problem.

This is a bug in pgfplots macro pgfplotsdefineaxistype, which uses an explicit 
\begin{axis} ... \end{axis} instead of the more portable \axis ... \endaxis. 
Attached is a quick fix, but it has been quite a while since I looked at 
pgfplots code, so it may be better to post a bug-report on pgfplots mailing 
list for a proper fix.

[NTG-context] Polar pgfplots seems to be broken

2020-12-20 Thread Gavin 
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
