Hi John, Thanks for compiling all of this information on this issue.
As recall from investigating this last time it came up, the current state is that 1) Babel relies on gnuplot-mode for session based evaluation 2) gnuplot-mode does not work on windows Which results in the need to add a ":session none" header argument on windows to avoid session based evaluation. I believe in this case gnuplot blocks will have to wait for an upstream fix to gnuplot-mode for sessions to work properly on windows. Some more comments inline below. If you could add this to the ob-doc-gnuplot page that would be much appreciated.

I've just replaced it in the repository, and updated the link so that it now points to the current version of org-check.org in the Worg repo on repo.or.cz, ensuring that the raw and exported file remain sync'd. > > I can run gnuplot fine from the Win command line.
