Seaborn: The solution of display chinese in seaborn plot

[githubzhanglei]

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.

Hi Elgins, I don't know anything about the Python3, :-)

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']})

@cqcn1991 When I try that I get this warning

/home/blomqvist/miniconda3/envs/notebook3/lib/python3.5/site-packages/matplotlib/font_manager.py:1288: UserWarning: findfont: Font family ['sans-serif'] not found. Falling back to Bitstream Vera Sans
  (prop.get_family(), self.defaultFamily[fontext]))

@viblo Seems like you are not under windows? Maybe you don't have 'SimHei' at all. Try changing it to a font that's available in your computer.

@cqcn1991 Right, Im on Ubuntu. I now got it to work, by using "Droid Sans Fallback" as my font. Thanks for the help!

I still think it would be good if seaborn could default to a good font by default so each user doesnt have to do this by themselves.

请问这个问题解决了吗？我也不行。。。

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.
