我如何在matplotlib中使用普通话字符? [英] How do you i use mandarin characters in matplotlib?

问题描述

我一直在尝试使用matplotlib的文本或用普通话汉字注释模块.它最终以某种方式显示框.有什么想法吗?

I have been trying to use matplotlib's text or annotate modules with mandarin Chinese characters. Somehow it ends up showing boxes. Any idea on this ?

推荐答案

以下是对我适用于Python 2.7和Python 3.3的解决方案，同时将text和annotate方法与中文一起使用.

Here is a solution that works for me on Python 2.7 and Python 3.3, using both text and annotate methods with Chinese.

import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
fig = plt.figure()
ax = fig.add_subplot(111)
ChineseFont1 = FontProperties(fname = 'C:\\Windows\\Fonts\\simsun.ttc')
ChineseFont2 = FontProperties('SimHei')
ax.text(3, 2, u'我中文是写得到的', fontproperties = ChineseFont1)
ax.text(5, 1, u'我中文是写得到的', fontproperties = ChineseFont2)
ax.annotate(u'我中文是写得到的', xy=(2, 1), xytext=(3, 4),
            arrowprops=dict(facecolor='black', shrink=0.05),
            fontproperties = ChineseFont1)
ax.axis([0, 10, 0, 10])
plt.show()

ChineseFont1被硬编码为字体文件，而ChineseFont2通过家族名称获取字体(但是对于ChineseFont2，我不得不尝试一对才能找到可行的字体).两者都是我的系统所特有的，因为它们引用了我拥有的字体，因此您很可能需要将它们更改为系统上的引用字体/路径.

ChineseFont1 is hard coded to a font file, while ChineseFont2 grabs a font by family name (but for ChineseFont2 I had to try a couple to find one that would work). Both of those are particular to my system, in that they reference fonts I have, so you quite likely will need to change them to reference fonts/paths on your system.

默认加载的字体似乎不支持汉字，因此主要是字体选择问题.

The font loaded by default doesn't seem to support Chinese characters, so it was primarily a font choice issue.
