I have :

  • Ubuntu 13.10 64 bit
  • wxMaxima 13.04.2 ( Maximy:5.31.3 )
  • Lisp:SBCL 1.1.1.0.debian
  • gnuplot version 4.6 patchlevel 4 last modified 2013-10-06

When I check terminals in gnuplot using :

set terminal 

then I do not see png terminal.

What should I do to change it ?

png terminal is related with gd library so I have to :

  1. install gd library

  2. reinstall gnuplot from source file

To set png as the output file format of your graph you need to set the following in your *.gnu file:

set terminal png
set output filename.png

  • the png terminal is not on the list of available terminals so I can not use it. The problem is why ? – Adam Dec 21 '13 at 13:59
  • How do you know it is not available, how did you check that? – jobin Dec 21 '13 at 15:29
  • run gnuplot , then type set terminal. Then you will have a list of all available terminals. png is not on that list. I think that is a problem with libpg and libz libraries – Adam Dec 21 '13 at 17:28

What worked for me to get the PNG terminal was typing,

sudo apt-get install libgd2-noxpm-dev

then re-compiling and re-installing gnuplot.

  • Why do we need to re-compile ? – Panther Apr 9 '15 at 23:48
