What is not working?

import matplotlib.pyplot as plt
from matplotlib import collections as mc
import numpy as np

segments = [ [(1,2),(3,4)],
             [(5,6),(7,8)] ]
lc = mc.LineCollection(segments, linestyles='solid', pickradius=5, zorder=2)
fig, ax = pl.subplots()

ax.add_collection(lc)
ax.autoscale()

plt.show()  # added this line to get window
fig.save('so.png') # to save as png

gives me the attached figure.
