[gradsusr] Help in showing the example of using maxloc()

[Charles Seman]

Ooi,

Please also see: http://grads.iges.org/grads/gadoc/gradfuncfndlvl.html

If you set for a horizontal (x,y) domain, you should get a field of 
pressure levels, each value displayed in the 2D plot representing the 
level of the maximum wind for that vertical column according to the 
search limits:

set x ... ...
set y ... ...
set lev 1000
set t ...
set gxout shaded
d fndlvl(wind,max(wind,lev=700,lev=1000),lev=700,lev=1000)

Hope this helps,
Chuck
