Matplotlib: Times New Roman appears bold

Question

Here is a minimal example, and the result (inside a Word doc

Answer 1

I recently experienced this problem when the matlibplot updated from 2.2.3 to 3.1.0. I tried a lot of answers here and from other websites, but the font "times new roman" still appeared bold. But I remembered last time when it was still 2.2.3, the font appeared normal. So I just replaced the font_manager.py in the 3.1.0 by the font_manager.py in the 2.2.3:

copy the font_manager.py in ..\anaconda\pkgs\matplotlib-2.2.3-py37hd159220_0\Lib\site-packages\matplotlib

and paste it here: ..\anaconda\pkgs\matplotlib-3.1.0-py37hc8f65d3_0\Lib\site-packages\matplotlib

I hope it helps.

Answer 2

Removing ~/.cache/matplotlib/ solved the problem for me.
