Draw Japanese with matplotlib on Ubuntu
Confirm that Japanese fonts are included (TakaoP Gothic is used this time)
fc-list | grep Takao
/usr/share/fonts/truetype/fonts-japanese-gothic.ttf:Takao P Gothic,TakaoPGothic:style=Regular
/usr/share/fonts/truetype/takao-gothic/TakaoPGothic.ttf:Takao P Gothic,TakaoPGothic:style=Regular
Set font
import matplotlib
from matplotlib.font_manager import FontProperties
font_path = '/usr/share/fonts/truetype/takao-gothic/TakaoPGothic.ttf'
font_prop = FontProperties(fname=font_path)
matplotlib.rcParams['font.family'] = font_prop.get_name()
f1 = plt.figure()
af1 = f1.add_subplot(111)
af1.set_title(u'Take it')
af1.set_xlabel(u'Horizontal axis')
af1.plot([1, 2, 3, 4], label=u'Eh')
af1.plot([2, 3, 3, 2], label=u'Bee')
plt.legend()
plt.draw()
Delete cache when it doesn't work (super important)
rm ~/.cache/matplotlib/fontList.cache
