Version 1.8 of Gnuplot.py has just been released.
+ Compatible with NumPy
+ Compatible with future python where "with" will be a reserved word
+ Added a 'pdf' terminal definition
+ hardcopy allows for terminal='svg'
See NEWS.txt for more details.
At a user's suggestion, I just configured a mailing list for Gnuplot.py users called (guess) firstname.lastname@example.org. Information about the mailing list (including subscription information) can be found at http://lists.sourceforge.net/lists/listinfo/gnuplot-py-users
Thanks to SourceForge for making this so easy!
