What operating system?
It should be that when the Gnuplot.Gnuplot object is destroyed, then its
self.gnuplot object should run out of reference counts and be destroyed.
That object is a GnuplotProcess object which holds a popen file object.
When the GnuplotProcess object is destroyed, the popen file object
should be closed and destroyed, which should end the gnuplot process.
At least that's the theory, and I've never had any trouble with it under
Linux. It could be that the close-on-delete behavior of popen is not
the same on your platform, or it could be that you are somehow holding a
reference to the Gnuplot.Gnuplot object when your program ends (maybe
via a circular reference?) Anyway, I should probably add a close()
method to the Gnuplot.Gnuplot object to insist that the process is ended
NOW (this will also be required if I ever get around to finishing off
Jython support for Gnuplot.py).
Yours,
Michael
