更改 Matplotlib 的默认字体 [英] Change Matplotlib's default font

问题描述

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.

I'm trying to change matplotlib's default font to Helvetica Neue. On my Mac with EPD/Canopy everything worked fine some time ago.

现在尝试在 ubuntu 上做同样的事情，但它不起作用.

Trying to do the same on ubuntu now and it's not working.

这就是我所做的:

1. 安装 Helvetica Neue

1. Installed Helvetica Neue

$ fc-match 'Helvetica Neue':Light
HelveticaNeue-Light.otf: "Helvetica Neue" "細體"

将 odt/dfont 转换成 ttf:

Converted the odt/dfont into ttf:

fondu -show HelveticaNeue.dfont

将 matplotlibrc 更改为

changed matplotlibrc to

$ 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

I removed the font cache

rm ~/.config/matplotlib/fontList.cache

但是这些步骤都不适合我.

But none of these steps are working for me.

    $ 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[fontext]))

版本是 1.3.0

    $ python -c 'import matplotlib; print  matplotlib.__version__'
    1.3.0

我也尝试将字体移动到 ~/.config/matplotlib/fonts/ttf 但它没有用.

I also tried moving the fonts to ~/.config/matplotlib/fonts/ttf but it didn't work.

按照建议，我尝试为特定文本选择特定字体.

As suggested I tried selecting a specific font for a specific text.

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')

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

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[fontext]))

However I seem to experience this problem only with this Helvetica/Helvetica Neue font. (prop.get_family(), self.defaultFamily[fontext]))

推荐答案

这不会永久更改您的字体，但值得一试.

This will not change your font permanently, but it's worth a try.

matplotlib.rc('font', family='sans-serif') 
matplotlib.rc('font', serif='Helvetica Neue') 
matplotlib.rc('text', usetex='false') 
matplotlib.rcParams.update({'font.size': 22})
