Extraneous line drawn using pyplot

Hello list. I am having trouble with an extraneous line drawn from my
last data point back to the first data point. I I don't quite know
why this is happening and was hoping someone could tell me what was
wrong. I have attached an example; the commands I used are copied
below.

Thanks,
Jeremy

Your data repeat itself twice.
Please check your data and report back if you still see the problem.
