Question

我在数据框中使用双字节名称并使用data.plot方法。但双字节名称无法在图标签中显示。（显示在附图中的红色框中）我该怎么办？

Answer 1

这应该通过在fonts目录中添加一些字体来修复。我刚刚问我们如何将字体添加到python目录中。显然，日语没有字体：

!ls /usr/local/src/conda3_runtime.v19/4.1.1/lib/python3.5/site-packages/matplotlib/mpl-data/fonts/ttf

我能做到。安装步骤如下：

!wget http://ipafont.ipa.go.jp/old/ipaexfont/ipaexg00201.php
!mv ipaexg00201.php ipaexg00201.zip
!unzip ipaexg00201.zip
!cp ipaexg00201/ipaexg.ttf $HOME/.local/lib/python2.7/site-packages/matplotlib/mpl-data/fonts/ttf/
!cp $HOME/.local/lib/python2.7/site-packages/matplotlib/mpl-    data/matplotlibrc $HOME/.config/matplotlib/
!echo 'font.family : IPAexGothic' >>   $HOME/.config/matplotlib/matplotlibrc
!rm -r $HOME/.cache/matplotlib/*
import matplotlib
print(matplotlib.rcParams['font.family'])
import matplotlib.pyplot as plt
%matplotlib inline
plt.figure()
plt.xlabel(u'豆腐 - tofu')
plt.title(u'豆腐 - TOFU')
