更改matplotlib的默认字体 [英] change matplotlib's default font

问题描述

我试图将matplotlib的默认字体改为Helvetica Neue。在我的Mac上使用EPD / Canopy前段时间一切正常。

试着在ubuntu上做同样的事情，它不工作。

这是我做的：
$ b

1. 安装了Helvetica Neue

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




2. 将odt / dfont转换为ttf：
   
   

     fondu -show HelveticaNeue.dfont 
     




3. 将matplotlibrc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 
     
    
    
    

这些步骤正在为我工​​作。

  $ 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：未找到字体家族['Helvetica Neue']。返回Bitstream Vera Sans 
  

（prop.get_family（），self.defaultFamily [fontext]））

版本是1.3.0

  $ python -c'import matplotlib;打印matplotlib .__ version__'
 1.3.0 
  

我也尝试将字体移动到〜/ .config / matplotlib / fonts / ttf 但是不起作用。

---

编辑：
建议我试着选择特定的字体文本。

pre $ 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'）


但是没有区别。

  /usr/local/lib/python2.7/dist-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg /matplotlib/font_manager.py:1236：
 UserWarning：findfont：未找到字体家族['Helvetica Neue']。回到Bitstream Vera Sans 
  

不过，我似乎只在这个Helvetica / Helvetica Neue字体。
（prop.get_family（），self.defaultFamily [fontext]））

解决方案

字体永久，但它是值得一试的

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

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

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

This is what I did:

1. Installed Helvetica Neue

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

2. Converted the odt/dfont into ttf:

   fondu -show HelveticaNeue.dfont
   

3. changed matplotlibrc to

   $ cat ~/.config/matplotlib/matplotlibrc
   ...
   font.family: Helvetica Neue
   

   I also tried with:

   font.family: sans-serif
   font.sans-serif: Helvetica Neue
   

4. I removed the font cache

   rm ~/.config/matplotlib/fontList.cache
   

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]))

Version is 1.3.0

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

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

EDIT: 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')

But it makes no difference.

/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]))

解决方案

This won't change you 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})
