Keep in mind, too, that in terms of matplotlib, for simple plots all you need to
feed the plot() function is a list of x points and a list of y points.  Sometimes
the demos on their web page might seem to obscure this for beginners because
of the fancy math functions that make pretty plots, but that's all you need:
two lists.

Getting those two lists of points is what you are really concerned about, as 
Kent indicated, and so this is not really a matplotlib concern.  And as he said,
Python has lots of good support for that.
