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.`
