[ferret_users] shade 3 args with time

[Brockmann Patrick <Patrick.Brockmann@xxxxxx>]

Hi all,

Is there a way to activate time labeling when a shade command is used 
with 3 args ?
It would be usefull to plot hovmoller plot from curvilinear model output.

Attached is a script using classic navy_winds netcdf file to simulate 
the problem.
Thanks

Patrick

!======================================
use monthly_navy_winds

!======================================
shade UWND[j=@ave]
frame/file=wish630_shade3args_time_01.gif

say 'normal'
pause

!======================================
let var=UWND[j=@ave]

let xpos=var*0+x[g=var]
set variable/units="degrees_east" xpos

let tpos=var*0+t[g=var]
set variable/units="seconds" tpos

shade var, xpos, tpos
frame/file=wish630_shade3args_time_02.gif

say 'vertical units are not in a date format'
