Answer 1

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

Answer 2

setenv("GNUTERM","qt") in your octave command prompt, it should solve the problem.
