Try something like

draw2d(
  explicit(exp(-tau^2/2),tau,0,1),
  ylabel = "f({/Symbol t})",
  xlabel = "Time,  {/Symbol t}",
  label(["f({/Symbol t}) = e^{-{/Symbol t}^2/2}",0.3,0.7]),
  user_preamble="set termoption enhanced");


This code worked in terminals (Gnuplot 4.4) jpg, png, gif, wxt and x11.

It didn't work with terminal svg. I don't know if it works in windows
terminal.
