I would like to recreate a plot I made in matlab in the past.  It is essentially
a time series of wind vectors with the vector origins all at the same Y value
and the X origin value corresponding to the date/time.  The vectors are drawn
with the u (East/West) and v (North/South) velocity components.  Does anyone
have any suggestions on how to do this.  I don't think it would be hard if I
could convert the dates to a date number, but I could not find what type of date
numbers are used when I looked in the documentation.  Your help will be much
appreciated!
