Python Pie

1, Example 1

Code

Import matplotlib.pyplot AS PLT
 Import numpy AS NP 
 plt.rcParams [ ' font.sans serif- '] = ' SimHei ' plt.rcParams [ ' axes.unicode_minus '] = False # generates data rng = np.random.RandomState (27 ) V = rng.randint (10, 50,. 4 ) groups = [ ' first group {} ' .format (I) for I in Range (. 1,. 5 )] # draw graphics plt.pie (v, labels = groups, = autopct ' % 1.1f %% ' ) plt.show ()

Graph

 

 

2, optimization of the FIG.

Code

Import matplotlib.pyplot AS PLT
 Import numpy AS NP 
 plt.rcParams [ ' font.sans serif- '] = ' SimHei ' plt.rcParams [ ' axes.unicode_minus '] = False # generates data rng = np.random.RandomState (27 ) V = rng.randint (10, 50,. 4 ) groups = [ ' first group {} ' .format (I) for I in Range (. 1,. 5 )] Qoffsets = [0, 0, 0, 0.07 ] # drawing graphics plt.pie (V, = Labels Groups, the explode = Qoffsets, autopct = ' % 1.1f %% ', startAngle = 90, Shadow = True) plt.show ()

1, Example 1

Code

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()

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()

图形
