What is an (x,y) plot alternative to matplotlib in Python?

Question

I've been trying for several hours to download/build/install/use matplotlib and am at my wit's end. I finally got it to build and it runs but doesn't display anything despite calling plt.show().

Is there an alternative to matplotlib? I just need something in Python to graph (x,y) data, in either lines or points. (I'm running Python 2.7 in Mac OSX 10.6)

edit: please point me at a source of binary installers for any reputable package besides matplotlib. Building from source code on my machine seem to have trouble for some reason.
