Python数据可视化详解（5/5）--------面积图、圆环图

面积图

import numpy as np
import matplotlib.pyplot as plt

x = [2,3,4,5,6,7]
y = [4,5,1,2,5,2]

plt.fill_between(x,y)
plt.show()

堆积的面积图

import numpy as np
import matplotlib.pyplot as plt

x = [2,3,4,5,6,7]

y2 = [[4,5,2,1,1,0],[1,24,5,3,2,1],[9,8,7,5,4,1]]
plt.stackplot(x,y2,labels=["A1","A2","A3"],colors=["green","blue","red"],
              alpha=0.4)
plt.savefig("2.jpg")

圆环图

import numpy as np
import matplotlib.pyplot as plt

plt.pie([1,23,7],
        wedgeprops={'width':0.6},
        startangle=0,
        colors=["green","blue","red"],
        labels=["A","B","C"])
plt.savefig("2.jpg")
