Hi Iris,
If you have a look at the script $FER_DIR/go/fland.jnl you can see how transparency can be achieved for both ferret and pyferret.
...
! transparency:
! in PyFerret use an opacity setting.
! in Ferret do a "checkerboard" plot which works in all plot modes.
if ($3"0|transparent>1|*>0") then
if ($program_name"0|PyFerret>1|*>0") THEN
define symbol fland_qual = /opacity=50
else
let ii = i[gx=rose]
let jj = j[gy=rose]
let plot_var = if mod(ii+jj,3) eq 0 then rose
endif
endif
...
Also you will want to do a SHADE overlay with a single colour rather than FILL
so something like
SHADE/over/opacity=50/pal=gray/nolab/nokey msl_signif_95
is probably what you want
Cheers,
Russ

Dear Ferret people,
I would like to plot the anomalies of a field and plot over it the areas of significance either with a hatched grid or dots. In the new version of PyFerret the option of plotting a pattern is not available:
yes? fill msl_anom
yes? fill/over/pat=large_grid msl_signif_95
**ERROR: invalid command: PATTERN style is not available in PyFerret
My significance variable (msl_signif_95) is already a mask.
Any ideas of how could I plot the areas of significance alternatively?
Thanks,
Iris
