When I was trying to use Chinese characters for a chart's title, matplotlib displayed a bunch of squares. Here are the steps to solve it.
Step 1: Find matplotlibrc
I am using virtualenv, so for me the path is:
~/.envs/edge/lib/python3.5/site-packages/matplotlib/mpl-data
The key part is /lib/python3.5/site-packages/matplotlib/mpl-data
Step 2: Modify matplotlibrc
Uncomment font.family and font.sans-serif, then add the following fonts before Bitstream Vera Sans:
PingFang SC, Hiragino Sans GB, Microsoft YaHei,
It should look like this:
font.sans-serif : PingFang SC, Hiragino Sans GB, Microsoft YaHei, Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
If you have a ipyton notebook open, you have to close and reopen it to make this change effective. Otherwise this is it :D
