Re: [ferret_users] More symbols In PLOT comand....

Hi Seon,
Yes, you can use the polymark script for your data. The example at the
start of the polymark script uses data that are defined as longitudes or
latitudes, but they can be any points defined by a set of x,y locations

Try it this way: Use PLOT/VS first, which makes some settings that the
polymark script needs. You might want to use /HLIMITS and /VLIMITS to
set the plot region a little larger so your points are not right on the
edges. Then the polygon command you send to the polymark script will
overwrite those symbols

define axis/x=1:1439:1 varx
define grid/x=varx varg
file/var="fr,gr"/grid=varg eige.dat
plot/vs/sym=21 x_val, y_val
go polymark poly/over/palette=blue/nokey/nolab x_val, y_val,,square

The x_val and y_val are the locations. The next argument is missing in
the example above, if you want all the polygons to be the same color.
There are a bunch of single-color palettes available and they are listed
at the end of the FAQ,
