This has horrible flickering, but at least this creates a plot that animates for me. It is based on Aron's, but Aron's does not work as-is.

import time, sys
from IPython.core.display import clear_output
f, ax = plt.subplots()

n = 30
x = array([i/10.0 for i in range(n)])
y = array([sin(i) for i in x])
for i in range(5,n):
  ax.plot(x[:i],y[:i])
  time.sleep(0.1)
  clear_output()
  display(f)
  ax.cla() # turn this off if you'd like to "build up" plots
plt.close()
