Python绘制饼图调节字体大小、防止标签重叠解决方法

设置字体的大小

patches,l_text,p_text=plt.pie(money_rate,explode=explode,labels=names,autopct=\'%.2f%%\')
# l_text是饼图对着文字大小，p_text是饼图内文字大小
for t in p_text:
    t.set_size(5)

for t in l_text:
    t.set_size(6)

防止标签重叠，可以将窗口设置的大一些

plt.figure(figsize=(20, 6.5))

3.源码

import matplotlib
import matplotlib.pyplot as plt
import numpy as np

matplotlib.rcParams[\'font.family\']=\'SimHei\'

names=np.array([\'正义联盟\',\'东方快车谋杀案\',\'密战\',\'寻梦环游记\',\'雷神3：诸神黄昏\', \'全球风暴\', \'降魔传\',\'追捕\',\'七十七天\',\'狂兽\',\'其它\'])
money=np.array([57767,22354,7916,15969,73853,14839,8725,8716,8318,6764,52222])
money_rate=money/np.sum(money)
explode=np.zeros((len(money)))
explode[4]=0.1

plt.figure(figsize=(20, 6.5))
patches,l_text,p_text=plt.pie(money_rate,explode=explode,labels=names,autopct=\'%.2f%%\')

plt.legend(["雷神3：诸神黄昏","正义联盟","东方快车谋杀案","寻梦环游记","全球风暴","降魔传","追捕","七十七天","密战","狂兽","其它"])
plt.legend(loc=\'center right\')
plt.title(\'电影排片占比\')
plt.axis(\'equal\')

# 设置饼图内文字大小

for t in p_text:
    t.set_size(5)

for t in l_text:
    t.set_size(6)
plt.show()
