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 tscannI 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
