How to display Chinese in pandas plot?
提问by joe
Here, I have a plot work to do with pandas, like this :
在这里，我有一个与Pandas有关的情节工作，如下所示：
most_active_posts.plot(x = 'title',y = 'active_span',kind = 'barh')
most_active_postsis an object of dataframe with index, I want a simple two-dimentional plot with two columns, one is 'title'and the other is 'active_span'.
most_active_posts是一个带索引的数据框对象，我想要一个简单的二维图，有两列，一个是'title'，另一个是'active_span'。
titleis type of string, which contains Chinese characters, while active_spanis type of integer .
title是字符串类型，包含汉字，active_span而是整数类型。
How can I display Chinese characters normally?

My work-around is like this:
我的解决方法是这样的：
import pandas as pd
import matplotlib.pyplot as plt
import matplotlib.font_manager as fm
font = fm.FontProperties(fname='c:\windows\fonts\simsun.ttc') # speicify font
ax = most_active_posts.plot(x = 'title',y = 'active_span',kind = 'barh')
ax.set_xticklabels(most_active_posts['title'].str.decode('utf-8'), fontproperties=font)
plt.show()
Basically, you need to specify a valid font for Chinese characters.
基本上，您需要为中文字符指定有效的字体。

I find a python library designed for fixing Chinese display in pip. You can download it using the command in your terminal:
我找到了一个专为修复pip中的中文显示而设计的python库。您可以使用终端中的命令下载它：
pip install pyplotz
And you can write the following code instead(full code):
您可以改为编写以下代码（完整代码）：
from pyplotz.pyplotz import PyplotZ
pltz = PyplotZ()
pltz.enable_chinese()
most_active_posts.plot(x='title',y='active_span',kind='bar')
pltz.xticks(np.arange(len(df.cn)),df.cn,rotation=360)
pltz.legend()
pltz.show()
And it can help you handle matplotlib Chinese font for you! This is the github page:

- Enter the directory
Lib\site-packages\matplotlib\mpl-data, and edit the filematplotlibrc. - Locate
font.familyandfont.sans-serifthen uncomment both of them and insetMicrosoft YaHeiafterfont.sans-serif.
- 进入目录

font.family并font.sans-serif取消注释它们并Microsoft YaHei在 之后插入font.sans-serif。

if you use pandas, you can use get_xticklabelsto get labels and then set them with set_xticklabels.
如果您使用Pandas，则可以使用get_xticklabels获取标签，然后使用set_xticklabels.
import matplotlib.font_manager as mfm
import matplotlib.pyplot as plt
font_path = "/System/Library/Fonts/STHeiti Light.ttc"
prop = mfm.FontProperties(fname=font_path)
df = pd.read_csv("data.txt"]
figure, ax = plt.subplots(figsize=(12, 4))
tmp = df.boxplot(by='shop', column='buy', ax=ax)
ax.set_xticklabels(tmp.get_xticklabels(), fontproperties=prop)
plt.show()

I think you want the characters to be the labels on the plot right?
我认为您希望角色成为情节上的标签，对吗？
I just grabbed some random characters:
我只是抓了一些随机字符：
In [40]: df
Out[40]:
0 title
0 0 ?
1 1 ?
2 2 ?
3 3 度
[4 rows x 2 columns]
I don't think there is a way to set y_ticklabelsfrom df.plot(), but you can set them from the returned axesobject:
我认为没有办法设置y_ticklabelsfrom df.plot()，但您可以从返回的axes对象中设置它们：
In [47]: ax = df.plot(kind='barh')
In [48]: ax.set_yticklabels(df['title'].str.decode('utf-8'))
Out[48]:
[<matplotlib.text.Text at 0x1152abfd0>,
<matplotlib.text.Text at 0x1152a3910>,
<matplotlib.text.Text at 0x111c5e790>,
<matplotlib.text.Text at 0x111c5ef10>]
In [49]: plt.draw()
Here's the figure:
这是图：
I'm not actually able to save the file and have the characters show up. Not sure why at the moment, but this may get you started.
我实际上无法保存文件并显示字符。目前不知道为什么，但这可能会让你开始。
