That's not correct. I have tons of Gnuplot.py based scripts which write directly to EPS output, without ever opening a gui window. Note that Gnuplot still tries to initialize the X11 terminal at startup, so they would require modifications to run over ssh without X forwarding. The default plot() command in Gnuplot.py doesn't make it too convenient to do this, but it's possible. The Gnuplot support in ipython (http://ipython.scipy.org) extends the syntax of the plot() command to make it trivial to render to EPS without a terminal. It shouldn't be hard to modify this to render to other formats, while avoiding opening an X11 window. Best, f -- http://mail.python.org/mailman/listinfo/python-list
