How to make IPython notebook matplotlib plot inline

Question

I am trying to use IPython notebook on MacOS X with Python 2.7.2 and IPython 1.1.0.

I cannot get matplotlib graphics to show up inline.

import matplo

I had the same problem when I was running the plotting commands in separate cells in Jupyter:

In [1]:  %matplotlib inline
         import matplotlib
         import matplotlib.pyplot as plt
         import numpy as np
In [2]:  x = np.array([1, 3, 4])
         y = np.array([1, 5, 3])
In [3]:  fig = plt.figure()
         
                      #this might be the problem
In [4]:  ax = fig.add_subplot(1, 1, 1)
In [5]:  ax.scatter(x, y)
Out[5]:    # CAN'T SEE ANY PLOT :(
In [6]:  plt.show()                                             # STILL CAN'T SEE IT :(

The problem was solved by merging the plotting commands into a single cell:

In [1]:  %matplotlib inline
         import matplotlib
         import matplotlib.pyplot as plt
         import numpy as np
In [2]:  x = np.array([1, 3, 4])
         y = np.array([1, 5, 3])
In [3]:  fig = plt.figure()
         ax = fig.add_subplot(1, 1, 1)
         ax.scatter(x, y)
Out[3]:  
         # AND HERE APPEARS THE PLOT AS DESIRED :)
