Hi Michael, I would recommending using a gnuplot code block rather than a plot line, and passing your data to the code block using a variable. Code blocks give you much more direct access to gnuplot, which I find generally makes gnuplot learning/debugging much easier.
see http://orgmode.org/manual/Working-With-Source-Code.html add something like this to your config (org-babel-do-load-languages 'org-babel-load-languages '((gnuplot . t))) then try something like the following Best -- Eric
