Adding 2 Line2D objects to a Subplot

Community matplotlib-users

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?

You might want to look at LineCollection objects.
