:output file is wrong (there's no header arg named :output).
:file chart.png says to write the results to that file. The "results"
are whatvever the variable `ans` holds at the end of the block, and I
think that must be the file path you're seeing.

One way to write that example is:

#+begin_src octave :results file
figure( 1, "visible", "off" );
sombrero;
print -dpng chart.png;

Escaping Square Brackets in LaTeX Export

Hi there,

I want to include the following in an org-mode buffer and be able to
export it to LaTeX:

#+begin_src python :exports code
s[0]
#+end_src

The problem is that org-mode treats s[0] as a footnote reference and
produces LaTeX like this:

\begin{verbatim}
s\footnote{DEFINITION NOT FOUND: 0 }
\end{verbatim}

Is it possible to escape the square brackets?

Thanks,
Richard

This works for me with both python and R code blocks on the latest version 
pulled from git.  Which version of org-mode are you experiencing this with?

In function org-edit-src-code there is already support for derived modes from org-mode:
,----
|   (let ((mark (and (org-region-active-p) (mark)))
| 	(case-fold-search t)
| 	(info (org-edit-src-find-region-and-lang))
| 	(full-info (org-babel-get-src-block-info))
| 	(org-mode-p (or (org-mode-p) (derived-mode-p 'org-mode)))
`----

(defun org-mode-or-derived-mode-p ()
  "Check if the current buffer is in Org-mode or a derived mode."
  (if (derived-mode-p 'org-mode) t nil))

Using org-mode-or-derived-mode-p would change the function like this:
,----
| In function org-edit-src-code
|   (let ((mark (and (org-region-active-p) (mark)))
| 	(case-fold-search t)
| 	(info (org-edit-src-find-region-and-lang))
| 	(full-info (org-babel-get-src-block-info))
| 	(org-mode-p (org-mode-or-derived-mode-p))
`----

org-mode-p could be replaced step by step with org-mode-or-derived-mode-p to enhance the support for
org-mode derived modes.

I need org-mode-or-derived-mode-p instead of org-mode-p in org-entry-properties.

It would be great if org-mode-or-derived-mode-p could be added!

Thanks,
  Stefan.

Thanks for the pointer. It led me to discover that some of my org-mode
libraries were coming from the Debian emacs package, and some from my
git repository. So a site-specific problem.  I've actually been caught
out by this before, so no excuse really.

Thanks,

How to suppress \label commands in beamer export

I'm trying to convert a presentation I've done in beamer to org-mode. I'm
going to improve this presentation and add more stuff to it. I'd like to do
it in org-mode.

However, org adds \label{sec-numbers} in the generated tex file after all
environments and this adds some blank space between the blocks in the final
presentation. I understand this extra blank space is more like a latex
issue, but I couldn't find a way to stop org-mode from creating the \label
lines.

In order to reproduce this, export the attached org file to a beamer
presentation. Notice how Block 1 and Block 2 (as well as Block 3 and
Block 4) have a lot of blank space between them. In fact, this makes Block
2 and Block 4 goes out of the frame.

Now, in the .tex file that org created, erase all the \label lines and
compile the file again. Notice how the blank space between the blocks
changes and now Block 2 and Block 4 fit nicely inside each frame.

Note: I use the overprint environment. The attached file has two lines that
must be executed in order to make overprint work. Maybe this environment
should be added to org-beamer-environments-default.
