One approach is to store the figure and axes into variables, and then 
manipulate and redisplay them in a subsequent cell:
fig, ax = subplots()
plot(linspace(-pi, pi, 100), sin(linspace(-pi, pi, 100)))
xlim(-pi, pi)

Out[0]: <plot with x limits at -pi to pi>


Out[1]: <plot with x limits at -1 to 1>
