Hi all, I'm also finding that "lev=xd" doesn't work in Ferret 6.3.For example, I have a field containing annual-mean screen temperature in Kelvin:
yes? stat tscann
Annual-mean screen temperature
LONGITUDE: 2.8W(-2.8) to 2.8W(357.2)
LATITUDE: 89.1S to 89.1N
Z: N/A
T: N/A
DATA SET: ./stsc_i04_climats_00201-01200.nc
Total # of data points: 3584 (64*56*1*1)
# flagged as bad data: 0
Minimum value: 214.63
Maximum value: 302.39
Mean value: 277.6 (unweighted average)
Standard deviation: 21.392
When I attempt to shade this data using the command
yes? shade/lev=2d tscann
I find that Ferret 6.3 selects contour levels ranging from 492 to 580. As
a result, I get a blank plot. The same shade command worked fine in
earlier versions.
By the way, the new "lev=xv" and "lev=xh" options are fantastic - I think they'll rapidly prove to be invaluable!
Cheers, Steven
Hi Ferreters,
I found that in Ferret 6.3, contour levels don't necessarily
cover the whole range when specified with lev=xD:
$ ferret
NOAA/PMEL TMAP
FERRET v6.3
Linux(g77) 2.4.21-32 - 09/29/09
6-Oct-09 09:00
yes? set data coads_climatology
yes? contour/l=1/lev=2D sst
yes? contour/l=1 sst
With "lev=2D", the SST field is plotted only down to 14 degC,
missing high latitudes.
This problem may be a glitch introduced in Ferret 6.3;
Ferret 6.2 shows the whole temperature range.
Regards,
Ryo
