[ferret_users] Re: stipple in a less dense dot

Hi -
The dot is the right choice to use. It's the smallest symbol available 
and is drawn via a call to the underlying graphics to make just a 
single-point mark.  You could decimate the data you're plotting, 
something along these lines:

   plot/over/nolab/vs/symbol=dot/color=black xpts[i=1:1000:10], 
ypts[i=1:1000:10]
