LaTeX document and BoundingBox eps file created by matplotlib

I am having a problem with including the eps file generated by matplotlib in a LaTeX document. The size of the figure does not seem to be recognized correctly, and the signature is superimposed on the figure.

See image below. This is an image of a latex document that includes drawings created by matplotlib. The LaTeX source file and the python source code for plotting are shown below.
