Plot an IPython Notebook figure inline with fig.show()?

I'm calling the inline mode for IPython Notebook using;

%pylab inline

And the following code plots a figure immediately at the cell;

fig = plt.figure()
axes = fig.add_axes([0, 0, 1, 1])

However I would like to create the plot/axes etc. in one cell, and plot later using maybe;

fig.show()

How do I gain more control of the inline mode? If I don't use %pylab inline, it creates the plot in a seperate window which I don't want (and it usually freezes the window).
