ummm how about set size 0.8, 1.0 ?

umm set grid does the trick
i actually was able to hack on polar.m to get the grid and the aspect ratio
stuff to work... i patterned it after the gnuplot demo file "poldat.dem"
set size .8, 1.0;
set nologscale;
set polar;
set grid;
set noborder;
the EXASPERATING thing is that i can now get PART of the CIRCLE! This is
where i gave up and called for help. Playing with yrange affects the plot
in ways that seem to make no sense
any suggestions will be appreciated....

this is probably a wise decision, it will wind up setting things back a
bit, but it just seems to be a bad idea to let this gnuplot thing hold
octave back...
