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.

tex error > tex error on line 18 in file /Users/Gavin/Documents/Computer/ConTeXt/Polar Plot Experiments/Untitled.tex: ! Undefined control sequence

\pgfplots@environment@polaraxis@ [#1]->\begin {axis}[#1,data cs=polar,axis type=polar] l.18 \startpolaraxis[]

16 \startsection[title={Polar Plot}] 17 \starttikzpicture % tikz code 18 >> \startpolaraxis[] 19 \addplot+[mark=none,domain=0:720,samples=600]{sin(4*x)}; 20 \stoppolaraxis 21 \stoptikzpicture 22 \stopsection

mtx-context | fatal error: return code: 256

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!
