Hi,
It looks as though the axis needs to be marked as a "depth" axis.
In the file, the coordinate variable needs an attribute
ST_OCEAN :positive = "down" ;
You can correct how Ferret sees the axis within the Ferret
session,
yes? use my_data
yes? set axis/depth `var,return=zaxis`
Then the "show grid" would have a minus sign showing the
direction of the axis
GRID GBT1
name axis # pts start
end subset

Dear
Ferreters,
I am
facing a problem for z axis for 50 vertical levels from
soda ocean temperature data . when I list the z axis it
look good to me as...
let
p=z[gz=var]
list p

but the
interesting thing is when I plot this data it is showing
me a reverse plot... which is attached in this email.

so I am
just confused that in data how this axis is defined I
tried using /order=xy-zt but that was not working.
I hope
to get some help
cheers,
