GNUPLOT + Ruby question

Hi,

I need a fairly advanced graphing soultion and it seems as though
GNUPLOT is one of the very few graphing solutions that i can use with
ruby. Java has JFreeChart, which Rocks.

Does anybody have experience with GNUPLOT + Ruby + Windows? If so, what
are the steps to get it all working? Any help is appreciated as I cant
get it working.

Thanks,

Chris
