Here, I have a plot work to do with pandas, like this :
most_active_posts.plot(x = 'title',y = 'active_span',kind = 'barh')
most_active_posts is an object of dataframe with index, I want a simple two-dimensional plot with two columns, one is 'title' and the other is 'active_span'.
title is type of string, which contains Chinese characters, while active_span is type of integer .
How can I display Chinese characters normally?
My work-around is like this:
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.
