trajectory plot + colorbar

[Michael Traub <mtraub@xxxxxxxxxxxxxxxxx>]

Hi,

I try to plot trajectories (lon vs. lat and colored the pressure 
height!) with following command

GO polymark POLY/OVER/NOLAB/KEY/LEVELS="(200,1000,100)" LON+360 LAT 
PRESS/100 circle 0.2)

How can I turn the colorbar, so that 200 is at the top of the colorbar 
and 1000 is at the bottom??

Thanks in advance

Michael
