import matplotlib.pyplot as plt
import numpy as np
x = np.arange( 0. , np.e, 0.01 )
y1 = np.exp( - x)
y2 = np.log(x)
fig = plt.figure()
ax1 = fig.add_subplot( 111 )
ax1.plot(x, y1, 'r' ,label = "right" );
ax1.legend(loc = 1 )
ax1.set_ylabel( 'y values for exp(-x)' );
ax2 = ax1.twinx() # this is the important function
ax2.plot(x, y2, 'g' ,label = "left" )
ax2.legend(loc = 2 )
ax2.set_xlim([ 0 , np.e]);
ax2.set_ylabel( 'y values for ln(x)' );
ax2.set_xlabel( 'same x for both exp(-x) and ln(x)' );
plt.show()

结果为:
以上这篇python matplotlib实现双y轴的实例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持服务器之家。
