Is there any way to use ternary axes in PGFplotsX.i had a stab at passing in raw latex arguments. But I guess it probably won’t be possible, since the choice of axis type is specified by choice of function eg Axis(args) or PolarAxis(args).

Pgfplots itself supports ternary axes, see [tikz pgf - Draw a surface on a ternary diagram with pgfplots - TeX - LaTeX Stack Exchange](https://tex.stackexchange.com/questions/276496/draw-a-surface-on-a-ternary-diagram-with-pgfplots) for instance.  
However I do not know if there is an interface to this in PGFplotsX.

Just adding a new instance similar to [PGFPlotsX.jl/axislike.jl at 5145243095622247e8419b1fb4d0fa7d87ac627e · KristofferC/PGFPlotsX.jl · GitHub](https://github.com/KristofferC/PGFPlotsX.jl/blob/5145243095622247e8419b1fb4d0fa7d87ac627e/src/axislike.jl#L69-L74) should be enough to support it properly.

[https://github.com/KristofferC/PGFPlotsX.jl/pull/269](https://github.com/KristofferC/PGFPlotsX.jl/pull/269) is a PR to add it
