matplotlib plotting... running code line by line vs in one chunk (Python)

I was practicing plotting in matplotlib, and I noticed that the following code works correctly when I run it as one big chunk, but not when I enter it line by line into the console (a blank figure window shows up, but the line does not). What gives?

import matplotlib.pylab as plt
fig,axes=plt.subplots()
axes.plot([1,2,3],[2,3,4])
plt.show()

I'm running Enthought Canopy, Python 2.7.6., matplotlib 1.3.1

Thanks!

P.S. What I find even stranger is if I subsequently type fig into the console, all of a sudden the correct plot pops up in the figure window.

plot at once or line by line interactively? – emesday Apr 24 '14 at 23:19
What does `big chunk` mean? Dose each line have a sample? – emesday Apr 24 '14 at 23:21
Big chunk means I copy and paste the entire code segment into the console, vs pasting in each line separately. – monkeybiz7 Apr 25 '14 at 01:05

And you need to clarify your question to get an answer. We should guess... what you ask. – emesday Apr 25 '14 at 01:15
