1D Time series with vector gxout

[Jeffrey Duda]

Gabriel,
I don't understand why your display statement reads d *const(u,0)*;v;mag(u,v)
(hopefully you can see the bold italic text for "const(u,0)").  That doesn't
sound right.  To get 2-D wind direction, you should say "d u;v;mag(u,v)".
If you want one length to be zero, just subtract that variable from itself
(e.g., "d u-u;v;mag(u-u,v)").

Hope this helps.

Jeff
