It shows text without editing maxout.gnuplot, xlabel is definitely 
generated by latex.

But  "old" approach is still not working, latex cannot compile 
introduction.tex:

draw2d(
explicit(
  sin(x),x,-10,10),
  user_preamble="
  set terminal epslatex size 10.5,6.62 color standalone colortext;
  set output '~/introduction.tex';
  set xlabel '$2\pi$';
  set samples 200;
  "
  );
