What's not enough? The docs also state (a bit above the babel lines):

#+begin_quote
Babel support for gnuplot requires that gnuplot be installed on your
system, along with gnuplot.el, an Emacs major mode for interacting
with gnuplot. You can install gnuplot.el with ELPA.
#+end_quote

From my min-config, you can see that enabling gnuplot in babel and
pointing to gnuplot.el are enough. Is this what you mean (that you
need gnuplot.el + the babel lines)?

You mean you didn't change your .init.el and yet it began working when
the exact same setup was previously not working?

See org-toggle-inline-images:
- http://orgmode.org/manual/Handling-links.html#fnd-6

After C-c C-c on both blocks in the test file I sent (you need the the
resultant image links in the file), I did C-c C-x C-v per the manual
and get the attached as the result.


Best regards,
