Matplotlib: how to show plot again?

Question

Let say I make a plot in Ipython Notebook, and after couples of cells, I want to render it again, so I can compare it with other plots.

How can I do it?

Answer 1

You can plot like this:

a = [1,2,3,4]
b = [3,4,5,6]
f = plt.figure()
f.add_subplot(111).plot(a, b,'-', color='black')

Then render again just by calling f.
