Hello,

You have to write some Gnuplot code in the gnuplot_preamble option.

If you want to test package draw, type

? xtics

for info and examples.

If you want greek letters, you need the eps terminal:

load(draw) $

draw2d(
   terminal = eps,
   xtics = {
      ["0",0],
      ["{/Symbol p / 2}",%pi/2],
      ["{/Symbol p}",%pi],
      ["3 {/Symbol p} / 4",3*%pi/2],
      ["2 {/Symbol p}",2*%pi]},
   explicit(sin(x),x,0,2*%pi)) $
