Sonification of KmPlot?

[Rich Morin]

I'm not sure I understand your description.  It sounds like you're
saying that the user can interact with the plot using the cursor
and get readings at specific points.  I'm not sure that this would
be very usable for a blind person.  Is there a way to get the code
to dump out a full set of coordinates for the plotted lines?
