Hi Kelin
(I am adding a cc to the Users List - you must have forgotten to send your question to the list address as well).
To ask for the PLOT/VS command to go beyond the x-values in the x variable, you need to add or subtract 360 from the x variable, depending on which direction it needs to be extended:
shade field[x=40e:400e]
plot/over/nolab/vs/symbol=dot/color=black stiple_a,stiple_b
plot/over/nolab/vs/symbol=dot/color=black stiple_a+360,stiple_b
plot/over/nolab/vs/symbol=dot/color=black stiple_a-360,stiple_b
The modulo x axis of your variable "field" causes Ferret to automatically do a similar operation when it does the SHADE command, but PLOT/VS doesn't apply a modulo operation to the x values it plots.

Dear Ansley and forum,
I have a question to ask: How to extend stippled mark? For example, if I plot in a ferret default sense,
shade field
plot/over/nolab/vs/symbol=dot/color=black stiple_a,stiple_b
then I got a normal stippling in the whole region but if I extend the display to, say, x=40e:400e, then
shade field[x=40e:400e]
plot/over/nolab/vs/hlimits=40e:400e:1/symbol=dot/color=black stiple_a,stiple_b
then I couldn't get what I want to get, i.e. no stippling west of 180E in the figure. No stippling in the Indian.
Would you kindly help me? I attached the netcdf and two figures.
Best,
Kelin
