It is a packaging issue indeed.

Is there an Octave bug to fix here?  Or is this a packaging issue that is outside of Octave?

Now octave’s plotting works. Here is a description of my steps to achieve this. The gnuplot binary is installed to


by using macports. This path is added to octave’s loadpath. The plotting now works, but the modified loadpath cannot be saved. I get the message ’invalid stream object’ from the program savepath.
In /Users/bokjellmert the path /usr/local/octave/3.8.0/bin is exported to PATH. Both before and after this export to PATH the visible components of PATH are, however, the same:

bos-iMac:~ bokjellmert$ echo $PATH
bos-iMac:~ bokjellmert$

Then octave’s plotting is working satisfactorily. I thank Pantxo Diribarne and Sven Oberg for their help.

In order to list available terminals, you need to run 'set terminal' from  inside a gnuplot session:

pdiribarne@gamb-port-dp:~$ cd /usr/local/octave/3.8.0/bin/
pdiribarne@gamb-port-dp:bin$ ./gnuplot

              qms  QMS/QUIC Laser printer (also Talaris 1200 and others)
               qt  Qt terminal
            regis  REGIS graphics language
              svg  W3C Scalable Vector Graphics driver
          tek40xx  Tektronix 4010 and others; most TEK emulators
          tek410x  Tektronix 4106, 4107, 4109 and 420X terminals
          texdraw  LaTeX texdraw environment

          unknown  Unknown terminal type - not a plotting device
            vttek  VT-like tek40xx terminal emulator
            xterm  Xterm Tektronix 4014 Mode

You can see that the only "on-screen" terminal seems to be qt (no x11, no wxt, no aqua). In octave 'setenv ("GNUTERM", "qt")' works fine for me.

In octave, "gnuplot_binary" returns "gnuplot", thus the first gnuplot binary in the path is run. I had to remove the other places where I have gnuplot installed (/sw in my case) from my PATH in order to run the expected gnuplot binary.

At least "gnuplot_binary" should point to the one shipped with the dmg installer, and GNUTERM should be set to "qt" by default as it's the only available terminal.

Basic facts. I am new to Octave. Computer: iMac, 2.7GHz, IntelIrisPro 5200, 16GB+fusion. Operating system: OSX 10.9.2. Installations: Xcode 5.0.2, XQuartz 2.7.5, binaries for GNU Octave 3.8.0 for OSX 10.9.1 installed from Octave Forge. I cannot get figures by the cli.

octave:1> x = 0:0.1:1; y = sin(x);
octave:2> plot(x,y)

gnuplot> set terminal aqua enhanced title "Figure 1" size 560 420  font "*,6" dashlength 1
         line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list

octave:3> figure(5)

gnuplot> set terminal aqua enhanced title "Figure 5" size 560 420  font "*,6" dashlength 1
         line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list

octave:4> available_graphics_toolkits
ans =
  [1,1] = gnuplot
octave:5> setenv("GNUTERM","X11")
octave:6> getenv("GNUTERM")
ans = X11
octave:7> getenv("X11")
ans =
octave:8> plot(x,y)

gnuplot> set terminal aqua enhanced title "Figure 5"  font "*,6" dashlength 1
         line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list

Only gnuplot_qt exists, and no list of available terminals is obtained

bos-iMac:~ bokjellmert$ cd /usr/local/octave/3.8.0/libexec/gnuplot/4.6
bos-iMac:4.6 bokjellmert$ find . -name gnuplot_qt -a
bos-iMac:4.6 bokjellmert$ find . -name gnuplot_x11 -a
bos-iMac:4.6 bokjellmert$ set terminal
bos-iMac:4.6 bokjellmert$

In bash, ’cat gnuplot_qt’ produces a large output ending with the lines
