Octave does not plot
PlotOctavePlot Problem Overview
When I try to plot a graph on GNU Octave, and try to use plot, it gives me the following output
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
I am using Mac OS X 10.9.2. I have tried using
octave:79> setenv("GNUTERM","X11")
but I still get the same error.
Plot Solutions
Solution 1 - Plot
setenv("GNUTERM","qt") in your octave command prompt, it should solve the problem.
Solution 2 - Plot
I think your problem comes from using the CLI.
As of January 2, 2014. If you're using OS/X 10.9 (Maverics) then you can opt to use integrated GUI from the binary package by downloading the Octave 3.8.0 .dmg. Use Octave-gui not Octave-cli, or otherwise start the GUI from the CLI.
A note about the gui from The Octave Home Page
>But because it is not quite as polished as we would like, we have decided to wait until the 4.0.x release series before making the GUI the default interface (until then, you can use the --force-gui option to start the GUI).
Solution 3 - Plot
The following worked out for me
- Uninstall any existing gnuplot on your OSX
brew uninstall gnuplot
-
Install gnuplot with either X or X11
brew install gnuplot --with-x -
Finally, set the GNUTERM to X11
setenv("GNUTERM","X11")
Solution 4 - Plot
And if you need Aqua terminal instead of X11 - this might help:
brew uninstall --force gnuplot
brew install gnuplot --with-aquaterm --with-qt4
You don't need to add setenv("GNUTERM","X11") or add GNUTERM env.var to octaverc file.
Solution 5 - Plot
I've got this problem too and solved by installing an Aquaterm for mac as mentioned here.
p.s. If you get warnings like "warning: could not match any font: *-normal-normal-10" as I did, try to check your /usr/local/etc/fonts/fonts.conf
Solution 6 - Plot
To install it without aquaterm:
brew cask install xquartz
brew install gnuplot --with-x
brew install octave
vim ~/.octaverc
setenv("GNUTERM", "X11")
graphics_toolkit("gnuplot");
Solution 7 - Plot
I got the same problem when using Octave-cli, and I just avoid this by using "Octave-gui".
Solution 8 - Plot
Download and install Aquaterm.
sudo wget https://gist.githubusercontent.com/tuvistavie/8466870/raw/9064b4b3dfb3644950b6f5745056f54f8d6e56c6/gnuplot.rb -O /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/gnuplot.rb
brew uninstall gnuplot
brew update && brew upgrade
brew tap homebrew/science
brew info gnuplot
brew reinstall gnuplot --aquaterm --qt --test
worked for me ref
