Dan Davison has a brief worg tutorial on using babel with octave at
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-octave-matlab.html
Amongst other things, he offers the following example block for
producing a figure:
#+begin_src octave :output file :file chart.png
figure( 1, "visible", "off" );
sombrero;
print -dpng chart.png
#+end_src
#+results:
[[file:chart.png]]
The figure seems to be (briefly) created (it pops up on my screen if I
change 'figure( 1, "visible", "off" );' to 'figure( 1, "visible",
"on");'; also the code provided does the right thing in the octave interpreter).
However, rather than delivering the png figure, the file chart.png
consists solely of the string "/usr/share/octave/packages/3.2". I'm
not sure where this string is coming from: it's *not* part of the
stuff that octave writes to stdout when the interpreter is invoked (my
first guess).
I suspect that the options that need to be offered on the #+begin_src
line have changed somehow since that worg page was last updated at the
end of April of this year, but don't really know.
Help!
