Python中plot使用方法小白的福音

直接上代码:

 1 import numpy as np
 2 import matplotlib.pyplot as plt
 3 from pylab import *
 4 
 5 mpl.rcParams['font.sans-serif'] = ['SimHei']
 6 def sigmoid(t):
 7     return 1. / (1. + np.exp(-t))
 8 x_plot = np.linspace(-10., 10., 5000)
 9 y_plot = sigmoid(x_plot)
10 plt.plot(x_plot, y_plot)
11 plt.show()
