Baptiste,

Thank you. The examples in the documentation for tikz helped me solve this problem, and give me a good tool for future plots. I only need to figure out how to incorporate LaTeX packages like amssymb so that I can use \mathbb{} to put the real numbers symbol in my plot.

Regards,

Michael
