[Matplotlib-users] Adding 2 Line2D objects to a Subplot

[Jose G. <sjm...@go...>]

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.

Here my dummy version:

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, 'r')

     #return line1+line2
     return line1


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

     ax.add_line(subplot_foo(i))

show()

First, the Line2D object does not represent the plot I want to create.
Second, I cannot collect various Line2D objects into a Subplot.

Any good idea around?
