In interactive mode, you should not be calling show() at all. And, you are mixing pylab and OO interfaces in a strange way; if you want to work interactively via the pylab interface, you should use pylab.cla() and pylab.clf(). If you want to work interactively but *mostly* with the OO interface, then you can call axes methods like clear(), but you need to put in pylab.draw() when you want the figure redrawn.
