Bug report

Bug summary

Trying to have a dynamic plot that gets created and iteratively updated in a single function, both in the notebook, and in the console:

Python 3.6.1 |Anaconda custom (x86_64)| (default, May 11 2017, 13:04:09) 
Type 'copyright', 'credits' or 'license' for more information
IPython 6.1.0 -- An enhanced Interactive Python. Type '?' for help.

Other software versions:

• notebook (5.1.0)
• ipywidgets (7.0.0)
• jupyter (1.0.0)
• jupyter-client (5.1.0)
• jupyter-console (5.1.0)
• jupyter-core (4.3.0)

Code for reproduction

In the notebook, this is preceded with %matplotlib notebook. Testing on the Mac for the console part. All one cell.

import matplotlib.pyplot as plt
import numpy as np
import time

fig = plt.figure()
fig.show()

for j in range(10):            
    plt.plot(range(0, j), [1/(i+1) for i in range(0, j)])
    fig.canvas.draw()
    time.sleep(.05)      

Actual outcome

1. in the notebook, the figure size changes (initial is small, final fills area)
2. in the console, the plot doesn't show up until all done plotting
