[pstricks] Accessing psfontdots

[Alan Ristow]

Hi,

I'm trying to access the dot symbols used for plotting so I can create a
legend. After trying to dissect the relevant parts of pstricks.tex, this
is the best I can come up with:

  \makeatletter%
    \newcommand*{\mychartdot}{%
      \addto at pscode{\psds at o}%
    }%
  \makeatother%

The idea is that I can use the command \mychartdot to create a circle
for my legend. The problem is, no dot shows up when I say \mychartdot
and I can't figure out why. I suspect I need something to follow \psds at o
in my definition -- perhaps say Dot, then issue a command to display Dot
-- but I haven't found the right combination yet.

I figure if I can get this part right I might try to package a set of
commands for making generic legends incorporating the pstricks dots --
that is, if Herbert doesn't rattle it off in his sleep as he usually
does. :-)
