Python 饼图

1、 示例1

代码

import matplotlib.pyplot as plt
import numpy as np

plt.rcParams['font.sans-serif'] = 'SimHei' plt.rcParams['axes.unicode_minus'] = False # 生成数据 rng = np.random.RandomState(27) v = rng.randint(10, 50, 4) groups = ['第 {} 组' .format(i) for i in range(1, 5)] # 绘制图形 plt.pie(v, labels=groups, autopct='%1.1f%%') plt.show()

图形

2、对上图进行优化

代码

import matplotlib.pyplot as plt
import numpy as np

plt.rcParams['font.sans-serif'] = 'SimHei' plt.rcParams['axes.unicode_minus'] = False # 生成数据 rng = np.random.RandomState(27) v = rng.randint(10, 50, 4) groups = ['第 {} 组' .format(i) for i in range(1, 5)] offsets = [0, 0, 0, 0.07] # 绘制图形 plt.pie(v, labels=groups, explode=offsets, autopct='%1.1f%%', startangle=90, shadow=True) plt.show()
