数据可视化之matplotlib实战：plt.scatter()函数 绘制气泡图

import matplotlib as mpl
import matplotlib.pyplot as plt
import numpy as np# 防止乱码
mpl.rcParams["font.sans-serif"] = ["SimHei"]
mpl.rcParams["axes.unicode_minus"] = Falsea = np.random.randn(100)
b = np.random.randn(100)# colormap:RdYlBu
plt.scatter(a,b,s=np.power(10*a+20*b,2),c=np.random.rand(100),cmap=mpl.cm.RdYlBu,marker="o")plt.show()
