If I replace that final line with pd 'save png ~user/temp/fig1.png' It works for me.
So that suggests a problem specific to your system. Some questions: (1) Have you installed all addons, and are they up to date? When I look at open'jwplot' I see this line: require 'graphics/afm graphics/color/colortab graphics/bmp graphics/png math/misc/trig' (2) If that doesn't get this working for you, it's possibly an architecture specific issue, in which case the contents of JVERSION on your system might help isolate the problem.
