Depending on what you are using gnuplot for, this might cause issues. For example, if using via an interactive desktop via SouthPass, using say plot sin(x) will fail. The terminal needs to be set to use x11. There are two ways to do this.:

Option 01: From the gnuplot command line:

Code Block
gnuplot> show t
   terminal type is qt 0 font "Sans,9"

gnuplot> set term x11
Terminal type is now 'x11'
Options are ' nopersist enhanced'
gnuplot>
gnuplot: unable to open display ''
gnuplot: X11 aborted.

gnuplot> show t
   terminal type is x11  nopersist enhanced

...
