Hi,
I have been playing some more with the new graphics system. Thanks
here to Mike Galloy for his new book for filling in some good
information.

There is one thing I have yet to find a solution to. I am using vector
to display some arrow on a world globe. However, without a reference
arrow which I can label with a quantity these plots, while pretty, are
useless. I have not been able to extract information for the the
length of a given arrow in devices coordinates (pixels). Is there a
way to get at this information? Once I know that, I can use the arrow
function to add the reference arrow.

Thanks,
Haje
