To install, you will need custom installs of fltk and graphicsmagick:
|
|
brew install --HEAD fltk
|
|
brew intalll graphicsmagick --with-magick-plus-plus
|
|

Octave 3.4.0 supports "native" plotting using OpenGL and FLTK. You can activate
|
|
it for all future figures using the Octave command
|
|
|
|
graphics_toolkit ("fltk")
|
|
|
|
or for a specific figure handle h using
|
|
|
|
graphics_toolkit (h, "fltk")
|
|
|
|
Otherwise, gnuplot is still used by default, if available.
|
|
EOS
|
|
|
|
gnuplot_caveats = <<-EOS.undent
|
|
When plotting with gnuplot, you should set "GNUTERM=x11" before running octave;
|
|
if you are using Aquaterm, use "GNUTERM=aqua".
