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
