PLOT/VLOG

will automatically select limits, PLOT/VLOG/VLIMITS=lo:hi lets you specify a range. The values are specified in data units, not log(units). This means that /VLIMITS can't start at 0.

I think you can use the command vlog for that

shade/l=1/vlog=0:1000/x=1 U[y=-90:90]

Hallo,

I have a simple question, I have zonal mean wind (U) data from NCEP,

and im just wondering how can I change the Z axis in ferret to log-pressure height?

shade/l=1/x=1 U[y=-90:90]

Thanks

Chang
