Re: [ferret_users] lines at grid boundries
Hi Ashley,
There are a few ways to do this kind of thing.
1) To make graticule lines across the plot, located at the tic marks of
any plot, use the /graticule qualifier on your plot command.
yes? SHADE/GRATICULE var
The Users Guide has more on this qualifier, which can be made so that
you control the horizontal and vertical graticules separately, and
choose the color and style of the lines drawn. Look under the plot
commands SHADE, PLOT, etc.
2) To plot the grid coordinate locations there is a family of scripts
gratxy.jnl, gratxz.jnl, etc which draw lines at the (X,Y) or (X,Z),
etc coordinate locations. See how these scripts work by typing
yes? go/help gratxy.jnl
Notice how the script sets specific levels and uses a CONTOUR command to
draw the lines; you might want to make your own version of the script
and change how the levels are specified if your coordinates are located
somewhere else than integer values.
3) Also, check the script gridlines.jnl which allows you to specify a
delta value in units of the coordinates, and will draw dashed lines at
the specified locations.
yes? go/help gridlines.jnl

Hi ferreters,
I am trying to draw lines that separate grid boxes. For example, I
have plotted the variable "rose" for selected region.
yes? use etopo20
yes? set reg/X=108E:112E/Y=3N:5N
yes? shade Rose
How can I draw graticule exactly at grid boundries on this plot.
Regards
Ashley
