import matplotlib.pyplot as plt

# data
x=linspace(0,1,10)
y1=x
y2=x**2

# Plot
fig = plt.figure(1)
ax = fig.add_subplot(111)
ax.plot(x, y1,label="y1"
ax. ...

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(10)

fig = plt.figure()
ax = plt.subplot(111)

for i in xrange(5):
    ax.plot(x, i * x, label='$y = %ix$'%i)

# Shrink current axis by 20%
box = ax.get_position()
ax.set_position([box.x0, box.y0, box.width * 0.8, box.height])

# Put a legend to the right of the current axis
ax.legend(loc='center left', bbox_to_anchor=(1, 0.5))

plt.show()

如果这个可以,分数给我偶像aprillf吧

y=x**2
fig= plt.figure()
ax =plt.subplot(111)

ax.plot(x,x,label='$y=x$')
ax.plot(x,y,label='$y=x^2$')

box=ax.get_position()
ax.set_position([box.x0,box.y0,box.width*0.8,box.height])
ax.legend(loc='upper left',bbox_to_anchor=(1.0,0.5))
plt.show()
