Matplotlib setting title bold while using "Times New Roman"

Question

Originally I can set the figure title to bold by the following:

import Matplotlib.pyplot as plt

plt.title("Test",fontweight="bold")

but once I use fontname="Times New Roman", fontweight="bold" just won't result in any change at all:

import Matplotlib.pyplot as plt

plt.title("Test",fontname="Times New Roman",fontweight="bold")

How shall I set the figure title to bold?

Answer 1

There's a bold times font of its own, assuming it's installed on your system:

plt.title("Test", fontname="Times New Roman Bold")

You can find a list of fonts on your system here: How to get a list of all the fonts currently available for Matplotlib?

I have:

>>> [i for i in matplotlib.font_manager.findSystemFonts(fontpaths=None, fontext='ttf')
if 'times' in i.lower()]
['/Library/Fonts/Times New Roman.ttf',
 '/Library/Fonts/Times New Roman Italic.ttf',
 '/Library/Fonts/Times New Roman Bold Italic.ttf',
 '/Library/Fonts/Times New Roman Bold.ttf']
