This comes up all the time. See this thread:
- http://lists.gnu.org/archive/html/emacs-orgmode/2012-07/msg00323.html
The key is to put it 1) before results (as you've done) and 2) to use
a named source block (with #+name: foo above your babel code) so that
Org knows what the results block actually is. Otherwise, as you
currently have it, if you re-run the babel block, you'll keep the
results section you already have and it will spit out another one
below it since it no longer recognizes that the babel block and
current, modified results block go together.
Good luck,
John

Greetings John.

Perhaps we could lower the frequency by making a small change to the
manual?

Done. For some reason not doing 2) also worked correctly, but I agree
that it is still a good idea to name the blocks.

Good point, thanks.

Yes, Eric fixed that problem some months ago, so the urgency of naming
code blocks has gone way down - but it should still be considered "best
practice" imo.

Oh, and not that it matters, but I typically do:
#+begin_center
#+ATTR_LATEX: :width 5cm
#+RESULTS:
[[file:triangle.pdf]]
#+end_center
Theoretically, more flexible for different types of exports. Even if
you're only doing LaTeX, it's still less characters to type :)

My recommendation is to always name code blocks: then the corresponding results
blocks are named as well, tying the two together; subsequent evaluations
will just refresh the appropriate results block without introducincg new
results blocks. This is not as much of a problem as it used to be, but
naming code blocks is still a good guideline, imo.
Other than that, I think that's the best that you can do.
