Octave-Gnuplot-AquaTerm error: set terminal aqua enhanced title "Figure 1"...unknown terminal type"
TerminalGnuplotX11OctaveHomebrewTerminal Problem Overview
I've installed Octave and gnuplot via Homebrew, and downloaded AquaTerm.dmg. When I try to plot, I get the following message:
octave:4> plot(x,y)
gnuplot> set terminal aqua enhanced title "Figure 1" font "*,6"
^
`line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list`
In a bash terminal set terminal
, set Terminal
, set term
, (and the same, followed by "aqua" too) etc gives nothing.
I've tried plotting again from octave having the "AquaTerm" already open, but nothing. I've tried plotting directly from gnuplot but same problem.. How can I do this "set terminal aqua"?
Gnuplot starting message says "Terminal type set to 'x11'
" but no idea how to change it, the previous commands didn't work neither.
Since AquaTerm wasn't installed from Homebrew maybe octave/gnupot can't find it... but no idea. Any guess? Thanks!
Terminal Solutions
Solution 1 - Terminal
I had to add setenv("GNUTERM","X11")
to OCTAVE_HOME/share/octave/site/m/startup/octaverc
(OCTAVE_HOME usually is /usr/local) to make it work permanently.

Solution 2 - Terminal
I've ran into a similar issue with Octave-cli, version 3.8.0, on OS X 10.9.1. Observing how Octave-gui could still plot charts, and reading up the answer with octaverc, I've got plotting to work from Octave-cli by adding a line with setenv("GNUTERM","qt")
to /usr/local/octave/3.8.0/share/octave/site/m/startup/octaverc
I didn't have to re-install gnuplot or other dependencies.
Solution 3 - Terminal
Setting the terminal type to x11 would solve the problem, but if you want to get AquaTerm working with gnuplot here's how:
First we need to uninstall the existing installation of gnuplot, open up a terminal and run this command.
brew uninstall gnuplot
Download AquaTerm from here: http://sourceforge.net/projects/aquaterm/ and install as you would any OSX application.
From here on, there are two ways to get gnuplot happy with aquaterm, Method 1 is easier, but didn't work for me because my AquaTerm installation didn't create the correct symlinks in /usr/local/lib, Method 2 is the one that worked for me, and I am sharing the steps I took to get it working.
Method 1: Simply reinstall gnuplot after installing AquaTerm seems to fix this issue for people.
brew install gnuplot
Go to the verify step to see if everything worked, if not, follow method 2
Method 2: This method is more advanced, but guaranteed to work if you are patient.
Essentially gnuplot cannot locate the AquaTerm library files, that's why aqua doesn't show up as a terminal type option after we installed gnuplot. We need to modify the homebrew recipe for gnuplot to enable aquaterm support, open up the brew recipe for gnuplot by typing:
brew edit gnuplot
And add these lines as shown in this github commit message, this will enable the brew option for gnuplot to include aquaterm https://github.com/mxcl/homebrew/issues/14647#issuecomment-21132477
Check to see if the proper AquaTerm library symlinks exist by doing these checks:
ls /usr/local/lib/libaquaterm*
ls /usr/local/include/aquaterm/*
The first line above should return some *.dylib files, the second line above should return some *.h files, if they do not exist run these commands from terminal:
sudo ln -s /Library/Frameworks/AquaTerm.framework/Versions/A/AquaTerm /usr/local/lib/libaquaterm.dylib
sudo ln -s /Library/Frameworks/AquaTerm.framework/Versions/A/AquaTerm /usr/local/lib/libaquaterm.1.0.0.dylib
sudo ln -s /Library/Frameworks/AquaTerm.framework/Versions/A/Headers/* /usr/local/include/aquaterm/.
This is necessary sometimes as the installer for AquaTerm can't create the symlinks in the correct places due to permission issues. Once the /usr/local/ symlinks are created, reinstall gnuplot like this:
brew install gnuplot --with-aquaterm # (formerly --aquaterm in old versions)
Verify that gnuplot can see aquaterm using the steps below and happy plotting!
Verify: that gnuplot was configured with AquaTerm correctly by launching gnuplot in terminal
gnuplot
Type this in the gnuplot terminal
gnuplot> set term
Look for the line
Available terminal types:
aqua Interface to graphics terminal server for Mac OS X
...
If you see the that line above, then you are done, gnuplot is configured correctly and everybody's happy.
Solution 4 - Terminal
I found a way to generate the plots with octave, although is not using AquaTerm but x11. The problem was that Octave was "forcing" gnuplot to use aquaterm to plot. Instead of installing and integrating aquaterm into gnuplot, in octave typed: setenv GNUTERM x11
. With this, plots are generated with x11 which is already in the terminal list of gnuplot (set terminal
). I know it's a patch, but finally I don't mind aquaterm or x11, I just want plots to be generated
Solution 5 - Terminal
set terminal
or set term
is gnuplot command.
You just need to run gnuplot
from command line to get access to the gnuplot shell.
However, this didn't work for me, neither did the setenv("GNUTERM","x11")
in /usr/local/share/octave/site/m/startup/octaverc
or ~/.octaverc
(both do the same thing).
So I ran set term
in gnuplot shell as saw no x11
in the list.
I used homebrew to install gnuplot, so I first uninstalled it brew uninstall gnuplot
, then installed with x11
using --with-x
flag for that:
brew install gnuplot --with-x
This solved the issue for me.
Use brew info gnuplot
to see the list of flags for gnuplot installation.
P.S. And yes, I did download an X11 dmg and installed it using package installer, still gnuplot had no x11 in the list of supported terminals.
Solution 6 - Terminal
You can try this:
>> brew reinstall gnuplot --with-aquaterm
or
>> brew uninstall gnuplot
>> brew install gnuplot --with-aquaterm
Solution 7 - Terminal
Create a file .octaverc
in your home directory and set GNUTERM to X11
echo "setenv('GNUTERM','X11')" > ~/.octaverc
Open octave terminal and type sombrero
to check whether plotting works
octave:1> sombrero
Solution 8 - Terminal
This worked for me:
-
Unistall gnuplot
> brew uninstall gnuplot
-
Install AquaTerm. You can download it from here: http://sourceforge.net/projects/aquaterm/
-
Reinstall gnuplot
> brew install gnuplot
Solution 9 - Terminal
Anton is correct. You can now just reinstall gnuplot with the --with-aquaterm option. I'd upvote his answer if I had enough reputation points to do it.
$ brew uninstall gnuplot
$ brew install gnuplot --with-aquaterm
Mackuntu mentioned above that this issue has been discussed on github.
https://github.com/mxcl/homebrew/issues/14647#issuecomment-21132477
But he advised using the option --aquaterm. If you take a close look at the github link you'll see that the option is --with-aquaterm. Reinstalling gnuplot with this option today allowed me to run some old octave code that uses gnuplot for plotting graphs on OS X.
Solution 10 - Terminal
In my case, on Mas OS Mojave, the solution that worked for my was slightly different (it could be a matter of syntax only). Following the discussion on this thread I came with the solution that worked for me - it might be important to note that it was possible for me to plot from the Octave-cli but not from Octave command line directly in terminal.
So I created a ˜/.octaverc
file and added the following command to it:
setenv GNUTERM qt
Just quit the command line from octave and entered again and was able to plot.
Solution 11 - Terminal
Following thing worked for me:
setenv("GNUTERM","qt")
You can either run it on the octave cli, for local run or can set in the octave startup file for permanent.
/usr/local/octave/3.8.0/share/octave/site/m/startup/octaverc
Just remember in case you change octaverc file you have to have write permissions on it.
Solution 12 - Terminal
I have an answer that should resolve the issue you're encountering. Essentially, for me the problem was that the gnuplot build did not locate the proper AquaTerm libraries. Check out the post I made:
http://deveneezer.blogspot.com/2013/06/octave-gnuplot-and-aquaterm.html
Solution 13 - Terminal
What has worked for me is installing gnuplot-nox. Also see https://bugs.mageia.org/show_bug.cgi?id=4866
Seems like the best way to install gnuplot-nox is to install fink. http://sourceforge.net/projects/fink/?source=dlp
fink install gnuplot-nox
seems to do a good job. However the installation was failing at one point. So I installed gnuplot-minimal then ran gnuplot-nox install again and everything worked just fine.
fink install gnuplot-minimal
fink install gnuplot-nox
gnuplot-nox install seemed to have set aqua as the default terminal for gnuplot. Verify that by going to gnuplot shell. To verify if plotting works, type plot(1) in the shell. It should show the plot in a window.
Hope that works for you.
Like suggested in other posts, setting GNUTERM to X11 didn't solve this issue for me. Also straight installing AquaTerm for Mac OSX didn't solve this issue.
Solution 14 - Terminal
The answer is already contained in the above, but this is simpler I think:
nano ~/.octaverc
add this:
setenv("GNUTERM", "X11")
Thats it restart octave you're done.
Solution 15 - Terminal
Here is the solution that worked for me (based on different parts of the mackuntu comment)
Gnuplot is probably already installed for you by the brew install octave command, so we need to remove it first
brew uninstall gnuplot
Then aquaterm has to be installed (http://sourceforge.net/projects/aquaterm/)
After install is complete you need to install gnuplot again. This is because brew detects the presence of aquaterm during install and will not do any checks for it after.
brew install gnuplot --with-aquaterm
If you launch gnuplot after install it should show that aquaterm is supported. And all graphics in octave will work.
