Adding 2 Line2D objects to a Subplot

Hi everybody

I wanted to collect a combination of plots to insert then in a subplot.
I choose to create Line2D objects to use the .add_line() method of the
AxesSubplot class, but unfortunately this does lead to the desired results.

Is the appended closer to what you had in mind?

from matplotlib.lines import Line2D
from matplotlib.pyplot import figure, show

import numpy as np

def subplot_foo(n):
     """ returns a the combination of 2 Line2D instances """
     x = np.arange(0, 200, 0.1)
     y = np.random.randn(len(x))
     print len(x)
     y2 = y+n

     line1 = Line2D(x, y, color = 'k')
     line2 = Line2D(x, y2, color = 'r')

     return line1, line2

fig = figure() # create Figure object
for i in range(1,5):
     ax = fig.add_subplot(2,2,i)

     subplots = subplot_foo(i)
     for subplot in subplots:
