Re: [ferret_users] stretched 2d grid

Hi James

you have a command that allows to control the dash intervals:
> plot/dash=(down1,up1,down2,up2) var
where down and up are in inches (see the tutorial for further details and
exemples)
If you prefer using something similar to xskip in vector, it is also
possible with this command:
> plot var[x=low:high:delta]
the choice of delta will determine how many points that will not be
plotted. For instance if you want to plot only one point on 3 for a
variable that contains 1000 points, the command will be:
> plot var[x=1:1000:3]
