The solution of display chinese in seaborn plot

As #829 and #592 said, the reason is “seaborn override default fonts specified in matplotlibrc configs”. Thus, you can set the default seaborn font style after import the seaborn as follows:

import seaborn as sns sns.set_style("darkgrid",{"font.sans-serif":['simhei', 'Arial']})

The simhei is the chinese font, and make sure the simhei.ttf already in your “Lib\site-packages\matplotlib\mpl-data\fonts\ttf” folder.

This method just change the seaborn font setting temporarily, however I do not know how to do that permanently.

Thanks @githubzhanglei , it works fine under python 3, here is my result. Just to be sure to set mpl first and then set seaborn.

import matplotlib as mpl
mpl.rcParams['font.sans-serif'] = ['SimHei']
mpl.rcParams['font.serif'] = ['SimHei']
import seaborn as sns
sns.set_style("darkgrid",{"font.sans-serif":['simhei', 'Arial']})

If still seeing error after putting SimHei.ttf into site-packages/matplotlib/mpl-data/fonts/ttf, you might try to clear font cache. For centos, just go to ~/.cache/matplotlib and remove cached font list file.
