Humm. This turns out to be a property of the PLOT
command that, frankly, I don't understand right
at the moment. Consider this:

IDL> x = [-0.96062616, 21.975719]
IDL> y = [0,14.7]
IDL> plot, x, y

But, now set the XRANGE:

IDL> plot, x, y, xrange=[0,15]

What do you make of that!? :-(

Cheers,

David
