Sadik and TideMan,
  Thank you both for your inputs.  Both solutions provided were correct and worked very well.  

TideMan,
  That was very crafty to think of defining an abscissa first.  I honestly didn't think of doing that because my script basically takes from a file, searches through it and plots a truth from two user defined points.  I would assume, the starting point that the user defines would be used as a started to plot.  I think I would've thought of Sadiks method before I thought of yours.  I appreciate your method.  Gives me a great direction to think of.

Sadik, can't leave you out.  Thank you for input as well.

Thanks to you both for your swift responses.
