tick direction

[Mr-Liu-CUG]

how to make tick direction inside the triangle，not outside?
for example ,I can adjust tick direction in matplotlib easily with sentence “plt.rcParams['xtick.direction'] = 'in'
plt.rcParams['ytick.direction'] = 'in'”
But, I do not know how to make it in ternary.
I would be very grateful if anyone could provide relevant suggestions

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 a look at the tick drawing functions in the library, basically one of the tick line endpoints would need to change to be on the inside of the plot and the ticks would need to be drawn above the other plot elements (a small or negative zorder should suffice).

Thank you very much for your detailed reply, thank you for giving me ideas
