circle symbol for plotting
greg severn
I'm running Linux 6.0, and the version of gnuplot (Linux version
3.7, patchlevel 0.2) that I have seems *not* to have open circles for
point type. I've tried pt 1-6 get boxes, triangles, crosses and
so on, but no circles. Can anyone tell me how to plot open and
closed circles, using for example
> plot 'stuff.dat' with points pt ? ps 5
Thanks!

Greg,
if you use postscript terminal for output then adding
one line to your gnuplot script you may replace say crosses (pt 2)
with circles:
set term postscript
set output 'tmp.ps'
plot 'stuff.dat' with points pt 2 ps 5
!sed 's/Crs$/Circle/g' tmp.ps > stuff.ps
sed looks for any occurrence of "Crs" (cross) at the end of line
(as in the prolog of postscript file where "Crs" is defined it is
not at the end of line) to replace it with "Circle".
The result is in 'stuff.ps'.

Greg,
sorry, in previous reply I complicated matters :).
postscript term itself offers circles. it is pt 6.
you may want to use command 'test' to check with
your terminal.

it's depend on what kind of terminal do you set.
when you used postscript terminal, you can
use point 31 (black circle) or 65, 71 (white)
Complete 75 point types for postscript terminal
can be found in the /doc/ps subdirectory of the
gnuplot distribution. You can compile the
"ps_symbols.gpi" with gnuplot.
I've already compiled this file; the gif image
be seen through my address:
http://warmada.dhs.org/Graphics/gnuplot/ps_symbols.html
When you want to set in latex terminal,
the close circle are the number from 10 to 12

You can see avilable point types with X11 terminal just typing
in gnuplot prompt;
gnuplot> test
Sorry, no open circle is supported with X11 termnal.
But you can use open circle with PostScript (same with Tgif) terminal.
If you execute AWK script following below, you can view point types
in PS (or Tgif) using GV.
$ awk -f marks.awk
$ gv marks.ps
Good luck!
