Perhaps "X-Y plot" is a something of a misnomer--what the "X-Y plot" 
really represents is the plot of some user-specified quantity along an 
arbitrary user-defined contour. The x-y plot is not nominally oriented 
at x=y=0. You can start and end the contour at any points that you desire.

When you then make a plot, the horizontal axis (or first column, if you 
are writing the info to disk) is a length in whatever units that you 
used when you drew the problem geometry. The horizontal axis always 
starts from zero, and this length represents the distance along the 
user-defined contour as measured from the starting point of the contour.
