 代码：

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0,10,1000)
y = np.sin(x)
z = np.cos(x*2.0)

plt.figure(figsize = (8,4))
plt.plot(x,y,label = "$sin(x)$",color="red",linewidth=2)
plt.plot(x,z,"b--",label="$cos(2*x)$")
plt.xlabel("time(s)")
plt.ylabel("Volt")
plt.title("PyPlot first Example")
plt.ylim(-2,2)
plt.legend()
plt.show()
