Subject: [babel] Producing figures from octave
Date: Wed, 31 Aug 2011 14:36:09 -0700	[thread overview]
Message-ID: <CAJ+2YJMD=G9YxFkKYWjdU=1GmE5wdFH+3yD1PEUuc9o4TpuSMA@mail.gmail.com> (raw)

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!
