When you use matplolib you should use the pylab APIs. this is because they
assume a persistant state to emulate a matlab notebook. This persistance is
a problem in web applications. First of all you have many concurrent
requests and they may interere with each other (not sure but I do not know
how pylab is implemented) and if you use it in a module the state may be
lost. Use the matplotlib API instead.
