You're getting that error because the second argument to FuncAnimation
(`result` in your example) should be a function (not always; see example 2
linked below). Right now, if your `showGraphs` function is defined in full,
it returns a value of None, which gets saved to `result` (hence the error).
You should take a look at some of the image animation examples
(ex1<http://matplotlib.sourceforge.net/examples/animation/dynamic_image.html>,
ex2<http://matplotlib.sourceforge.net/examples/animation/dynamic_image2.html>
).
