How do I include greek letter in gnuplot?

I'm using ubuntu 14.04 and gnuplot-x11, and found that for greek letter alpha,

{/symbol a} will work, but that just shows me {/symbol a}, not greek letter alpha.

I tried {\symbol a} or other options, but that does not work..

After using enhanced mode, take care for using {/Symbol a}, you have used {/symbol a}, small letter of "s" in Symbol, so you were not getting greek letter alpha.

Using the syntax {/Symbol a} requires that you enable the enhanced mode. This can be done in several ways:

  1. When setting the terminal

    set terminal ... enhanced

  2. After setting the terminal with

    set termoption enhanced

  3. Explicitely for a single label

    set xlabel '{/Symbol a}' enhanced

Depending on the output terminal you are using, the best option is to use utf-8 encoding and directly input the characters:

set encoding utf8
set xlabel 'α'
