如下所示:
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三水点靠木。
