Re: plotting to a .ps file

[Paul Laub]

Dear Christian, 

Have you tried immediately following your replot command with 

    gset output

that is, sending gnuplot a "set output" command with no filename
argument? Doing so will close the file handle opened to (in your
example below) "foo.ps". See gnuplot documentation for details.

Also, you might try sending gnuplot commands to gnuplot using octave's graw(). 

Finally, typing "show terminal" and "show output" at the gnuplot (not
octave) prompt might provide some clues.
