John & Eric,

Another approach, which I use and which doesn't require using the
development version of gnuplot for the tikz support, is to generate
encapsulated postscript files:

  set terminal postscript eps enhanced 20
  set output "graph.eps"

for instance.  Then, if I need bitmap images, I use "convert" from
ImageMagick to create these from the EPS files with the required
density (depending on intended use, whether screen display or
printing), as in

  convert -quality 95 -density 300 graph.eps graph.png

With EPS, you can get very nice looking text, especially with the
"enhanced" gnuplot set terminal option and the result is size
independent.
