change font, and output an equilateral triangle

[forgetmenot9911]

Hello! Thanks for listening my issues.

1. How can I change the font into another one, like Times New Roman?
2. Can I get an equilateral triangle? I copied the given code, made some modifications, ran it, and got this:

my code is:

import ternary

scale = 40
figure, tax = ternary.figure(scale=scale)

# Draw Boundary and Gridlines
tax.boundary(linewidth=1.0)
tax.gridlines(color="grey", multiple=5)

# Set Axis labels and Title
fontsize = 12
offset = 0.14
# tax.set_title("Triangle Plot\n\n", fontsize=fontsize)
# tax.right_corner_label("X", fontsize=fontsize)
# tax.top_corner_label("Y", fontsize=fontsize)
# tax.left_corner_label("Z", fontsize=fontsize)
tax.left_axis_label("Left label", fontsize=fontsize, offset=offset)
tax.right_axis_label("Right label", fontsize=fontsize, offset=offset)
tax.bottom_axis_label("Bottom label", fontsize=fontsize, offset=offset)

# Draw lines parallel to the axes
tax.horizontal_line(16)
tax.left_parallel_line(10, linewidth=2., color='red', linestyle="--")
tax.right_parallel_line(20, linewidth=3., color='blue')

# Draw an arbitrary line, ternary will project the points for you
p1 = (22, 8, 10)# bottom, right, left
p2 = (2, 22, 16)
tax.line(p1, p2, linewidth=3., marker='*', color='purple', linestyle=":")

tax.ticks(axis='lbr', multiple=5, linewidth=1, offset=0.025)
tax.get_axes().axis('off')
tax.clear_matplotlib_ticks()
# tax.show()
tax.savefig('test_triangle.png',dpi=600)

1. Font setting:
   a. You can change the font in global setting (more here)

import matplotlib.pyplot as plt
plt.rcParams["font.family"] = "Times New Roman" 

Make sure the font is available in your system. To check the available font family in your python environment

import matplotlib
print(matplotlib.font_manager.get_font_names())

b. If you want to change the font locally. Pass the font name by kwargs.

tax.left_axis_label("Left label", fontsize=fontsize, offset=offset, fontdict={'fontname':'Go'})

2. Equilateral triangle:
   Add this at the end

tax.get_axes().set_aspect(1)
