change matplotlib's default font
提问by gozzilli
I'm trying to change matplotlib's default font to Helvetica Neue. On my Mac with EPD/Canopy everything worked fine some time ago.
我正在尝试将 matplotlib 的默认字体更改为 Helvetica Neue。在我的带有 EPD/Canopy 的 Mac 上，前段时间一切正常。
Trying to do the same on ubuntu now and it's not working.
现在尝试在 ubuntu 上做同样的事情，但它不起作用。
This is what I did:
这就是我所做的：
Installed Helvetica Neue
$ fc-match 'Helvetica Neue':Light HelveticaNeue-Light.otf: "Helvetica Neue" "細體"Converted the odt/dfont into ttf:
fondu -show HelveticaNeue.dfontchanged matplotlibrc to
$ cat ~/.config/matplotlib/matplotlibrc ... font.family: Helvetica NeueI also tried with:
font.family: sans-serif font.sans-serif: Helvetica NeueI removed the font cache
rm ~/.config/matplotlib/fontList.cache
安装 Helvetica Neue
$ fc-match 'Helvetica Neue':Light HelveticaNeue-Light.otf: "Helvetica Neue" "細體"将 odt/dfont 转换为 ttf：
fondu -show HelveticaNeue.dfont将 matplotlibrc 更改为
$ cat ~/.config/matplotlib/matplotlibrc ... font.family: Helvetica Neue我也试过：
font.family: sans-serif font.sans-serif: Helvetica Neue我删除了字体缓存
rm ~/.config/matplotlib/fontList.cache
But none of these steps are working for me.
但是这些步骤都不适合我。
$ python -c 'from matplotlib import pyplot as plt; plt.plot(1); plt.savefig("/tmp/test.png")'
/usr/local/lib/python2.7/dist-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/font_manager.py:1236:
UserWarning: findfont: Font family ['Helvetica Neue'] not found. Falling back to Bitstream Vera Sans
(prop.get_family(), self.defaultFamily[fontext]))
(prop.get_family(), self.defaultFamily[fonttext]))
Version is 1.3.0
版本是 1.3.0
$ python -c 'import matplotlib; print matplotlib.__version__'
1.3.0
I also tried moving the fonts to ~/.config/matplotlib/fonts/ttfbut it didn't work.
我也尝试将字体移动到，~/.config/matplotlib/fonts/ttf但没有用。
EDIT:As suggested I tried selecting a specific font for a specific text.
编辑：按照建议，我尝试为特定文本选择特定字体。
import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt
import matplotlib.font_manager as font_manager
path = '/home/<myusername>/.fonts/HelveticaNeue.ttf'
prop = font_manager.FontProperties(fname=path)
prop.set_weight = 'light'
mpl.rcParams['font.family'] = prop.get_name()
mpl.rcParams['font.weight'] = 'light'
fig, ax = plt.subplots()
ax.set_title('Text in a cool font', fontproperties=prop, size=40)
plt.savefig('/tmp/test2.png')
But it makes no difference.
但这没什么区别。
/usr/local/lib/python2.7/dist-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/font_manager.py:1236:
UserWarning: findfont: Font family ['Helvetica Neue'] not found. Falling back to Bitstream Vera Sans
However I seem to experience this problem only with this Helvetica/Helvetica Neue font. (prop.get_family(), self.defaultFamily[fontext]))
然而，我似乎只有使用这种 Helvetica/Helvetica Neue 字体才会遇到这个问题。(prop.get_family(), self.defaultFamily[fonttext]))

This won't change you font permanently, but it's worth a try
这不会永久改变你的字体，但值得一试
matplotlib.rc('font', family='sans-serif')
matplotlib.rc('font', serif='Helvetica Neue')
matplotlib.rc('text', usetex='false')
matplotlib.rcParams.update({'font.size': 22})

Upload the fonts
上传字体
sudo cp NotoSansKR-Regular.otf /usr/share/fonts/
Update the cache of font
更新字体缓存
sudo fc-cache -fv
You can check the font list
您可以查看字体列表
fc-list
Restart ipython, etc. Check the font list
重启ipython等查看字体列表
[f.name for f in matplotlib.font_manager.fontManager.ttflist]
Take a your font name
取一个你的字体名称
import matplotlib.pyplot as plt
from matplotlib import rcParams
rcParams['font.family'] = 'Noto Sans Korean'
Draw
画
plt.title(u'?? ??')
plt.xlabel(u'?? ? ??')
plt.plot(range(5))

The font cache shows up in a different place for me (.cache/matplotlib/fontList.cache). And before I actually had three of them in different places somehow :/
字体缓存对我来说显示在不同的地方（.cache/matplotlib/fontList.cache）。在我实际上以某种方式将其中三个放在不同的地方之前：/
maybe try searching for it in your home directory:
也许尝试在您的主目录中搜索它：
find ~/ -name fontList.cache -exec rm {} \;

Kim already introduced dynamic solution works perfectly, and here's two other ways doing the same in static.
Kim 已经介绍了动态解决方案工作得很好，这里有另外两种方法在静态中做同样的事情。
First, you may put a line to rc file for matplotlib . Refer to this pagefor more information about locating the file and detailed settings.
首先，您可以在 rc 文件中为 matplotlib 放置一行。有关查找文件和详细设置的更多信息，请参阅此页面。
font.family : NanumGothic
Second, if you are working with ipython, you can put some commands for font setting to a configuration file for the interactive shell. Find the file named ipython_config.py which usually located under ~/.ipython/somewhere. Then add two more lines to the list, c.InteractiveShellApp.exec_lines .
其次，如果您正在使用 ipython，您可以将一些用于字体设置的命令放入交互式 shell 的配置文件中。找到名为 ipython_config.py 的文件，它通常位于 ~/.ipython/somewhere 下。然后再向列表中添加两行 c.InteractiveShellApp.exec_lines 。
c.InteractiveShellApp.exec_lines = [
"import matplotlib as mpl",
"mpl.rcParams['font.family'] = 'NanumGothic'"
]
Former always works whatever environment you run your shell script on as it loads the font when your script imports matplotlib .
前者始终适用于您运行 shell 脚本的任何环境，因为它会在您的脚本导入 matplotlib 时加载字体。
