Dear AndrewFalkowski,
Nice. Yes, it is certainly possible. If I understood correctly, your example plot is the triangular version of

If this is the case, then you can use the python-ternary to plot the data points. The only thing you have to care about is how to read those data and accordingly the axis ticks. Below is a test example.

import ternary, random
import matplotlib.pyplot as plt

points = [(10,10,80),(40,20,40)]
### Scatter Plot
scale = 100
axes_colors={'b':'r','l':'b','r':'k'}

figure, ax = plt.subplots(figsize=(10,10))
tax = ternary.TernaryAxesSubplot(ax=ax,scale=scale)

tax.set_title("Scatter Plot", fontsize=20)
tax.boundary(linewidth=2.0, axes_colors=axes_colors)
tax.gridlines(multiple=5, left_kwargs={'c': axes_colors['l']}, right_kwargs={'c': axes_colors['r']}, horizontal_kwargs={'c':  axes_colors['b']},linewidth=1)

tax.scatter(points, marker='s', color='red', label="test")

tax.legend()
tax.ticks(axis='l', linewidth=1, multiple=10, clockwise=True, axes_colors={'l':'r'})
tax.ticks(axis='b', linewidth=1, multiple=10, clockwise=False, axes_colors={'b':'b'})
tax.ticks(axis='b', linewidth=1, multiple=10, clockwise=True, axes_colors={'b':'k'})

tax.get_axes().axis('off')
tax.clear_matplotlib_ticks()
tax.get_axes().set_aspect(1)

tax.show()
