Re: samplexy

[Ansley Manke <ansley@xxxxxxxxxxxxx>]

Hi Martin,
I get a result running Ferret version 5.0, with this Ferret script
and the
levitus_climatology data, which is part of the Ferret release. 
Can you
run this?   It is possible that your version of Ferret has
a  bug in
SAMPLEXY, and that the solution will be for you to download a more
recent veraion of Ferret, since yours is a couple of releases back.

use levitus_climatology
let pente=-0.37
let xpts=34+j[j=1:60]*pente
let ypts=j[j=1:60]

!  Check the location of xpts,ypts
shade/k=1 temp
plot/vs/over xpts,ypts

! Sample temp and plot the profile
let profil = samplexy(temp,xpts,ypts)
stat profil
shade profil

Dear Ferret users,

I'm trying to use the SAMPLEXY function. Following the example in the
users guide, I've been able to draw a line through my domain:

yes? let pente=-0.37
yes? let xpts=34+j[j=1:60]*pente
yes? let ypts=j[j=1:60]
yes? PLOT/VS/LINE/SYM=27 xpts,ypts

But when I try to make a fill contour plot, I get this:

yes? let profil = samplexy(o3,xpts,ypts)
yes? fill /L=10 profil
 **ERROR: all data have same value: data are all flagged as bad

Variable "o3" is defined on 4 dimensions:
name     title                             I         J         K
L
 O3                                        1:45      1:60      1:12
1:31

I'm using FERRET (V500beta1.1), on SunOS 5.6.

Thank's for help.
