I don't have a good answer for using /pattern, but I do have an
alternative way to do this kind of thing, and it'll work fine with
any of the graphics modes.
Define a set of points on a grid, based either on the grid of the
variable being plotted, or a coarser or finer grid on the same
region, and plot the points using PLOT/VS/SYMBOL=dot, or another
shape. Here's a simple example:
yes? set data coads_climatology
yes? fill/lev=(0,33,3)/nolabel sst[l=1]
yes? go fland
yes? let xdot = x[gx=sst] + 0*y[gy=sst]
yes? let ydot = 0*x[gx=sst] + y[gy=sst]
yes? let mask = if sst gt 21 then 1
yes? plot/vs/over/sym=dot/nolab mask*xdot,mask*ydot
See what you think.
I imagine another idea might be to make a large gif and convert it
to eps using third-party software.
maybe this question has already been addresses, but I didn't find any working
I create a map and then stipples with the command:
How can I save the resulting plot in high quality eps?
Saving the map in gif works fine, but when I use Fprint -o Map.eps -p portrait
-R metafile.plt all the stipples are messy. Any advice?
