如何设置自定义字体与matplotlib全球字体的自定义路径？ [英] how to set up a custom font with custom path to matplotlib global font?

问题描述

在我的应用程序中有一个自定义字体

  app_path ='/ home / user1 / myapp'
 fname ='/ home / user1 / myapp / font / myfont.ttf'
  

要将 globlal 字体设置为matplotlib，文档将如下所示：

  plt.rcParams [ font.sans-serif'] = ['xxx font'] 
  

已经在系统字体路径中，我必须在我的应用路径中使用我的自定义字体'/home/user1/myapp/font/myfont.ttf'

我知道有这样一个方法：

pre $ f $ = fname ='/ home / user1 / myapp / font / myfont .ttf'
myfont = fm.FontProperties（fname = fname）
ax1.set_title（'title test'，fontproperties = myfont）

但是这并不是我想要的，我不想一直设置' fontproperties '，因为有很多代码需要更改

解决方

  import matplotlib.font_manager as font_manager 
 
 font_dirs = ['/ my / custom / font / dir'，] 
 font_files = font_manager.findSystemFonts（fontpaths = font_dirs）
 font_list = font_manager.createFontList（font_files） 
 font_manager.fontManager.ttflist.extend（font_list）
 
 mpl.rcParams ['font.family'] ='我的自定义字体'
  

fontpaths kwarg也可以是一个字符串，以防您只有一个目录从中导入。

希望这可以帮助那些未来绊倒人的人=）

There is a custom font in my app

app_path='/home/user1/myapp'
fname='/home/user1/myapp/font/myfont.ttf'

To setup globlal font to matplotlib,the docs said like this:

plt.rcParams['font.sans-serif']=['xxx font']

But it only works when the font already in system font path,and I have to use my custom font in my app path '/home/user1/myapp/font/myfont.ttf'

I know there is a way like this:

fname='/home/user1/myapp/font/myfont.ttf'
myfont=fm.FontProperties(fname=fname)
ax1.set_title('title test',fontproperties=myfont)

But that is not what I want,I don't want to set 'fontproperties' all the time,because there are some much code to change

解决方案

Just had exactly the same problem and managed to solve it like this:

import matplotlib.font_manager as font_manager

font_dirs = ['/my/custom/font/dir', ]
font_files = font_manager.findSystemFonts(fontpaths=font_dirs)
font_list = font_manager.createFontList(font_files)
font_manager.fontManager.ttflist.extend(font_list)

mpl.rcParams['font.family'] = 'My Custom Font'

The fontpaths kwarg can also be a string in case you only have a single directory to import from.

Hope it helps people who stumble across this in the future =)
