Hi, it looks pretty good on the notebook of examples. However on the example in `colorbar_kwargs.py` the lower labels intersect the lower axis labels so I think we'd need to...

There is currently no built-in way to do this. Ternary draws the ticks explicitly rather than using matplotlib's axes, so this would have to be added to the library. Take...

Thanks @maximweb !

Hi @zhongjingjogy, Very nice! I'm certainly willing to merge something like this in, provided the API is consistent, but it's not something I'm currently working on.

So I can't speak to what Plotly is doing, but I think one difference is that `ternary` assumes that the coordinates to be plotted [sum to a constant](https://en.wikipedia.org/wiki/Ternary_plot), in this...

It could be useful to check that the sum isn't equal to `scale` (and maybe that the values are all positive) warning the user if not. If you'd like to...

Hi @cmacdonald, do you want to open a PR with a change to the readme where you would have liked a warning / statement? You should be able to do...

Hi, thanks for the suggestions. The wikipedia page on [ternary plots](https://en.wikipedia.org/wiki/Ternary_plot) explains the coordinates have to sum to a constant. There's a link to the wikipedia page on the top...

So basically you want to be able to pass through arguments to `ax.fill` ? That seems fine to me.

There's no built in function like matplotlib provides. The easiest way is to write an interpolation function and use `heatmapf` or to compute your own dictionary.
