Example on front page of web site missing a line


I was checking out matplotlib, and tried running the example shown on
the front page (http://matplotlib.sourceforge.net/), but no window
showed itself. I had to look through the examples files to find out
how to make it work: it needed a show() command at the end. I think
that the example should be complete enough for the prospective user to
actually get a pretty picture... not just leave one hanging with <a
