A little more information now I've gotten to downloading the gnuplot package. There seem to be a lot of problems with Chart::Gnuplot.

Amongst others,

you need to code the output file thusly: output => 'c:\\\\test\\\\test.png', in order to get 'c:\\test\\test.png' into the command file. Otherwise you get the Invalid Parameter - 90 error.
You'll also get that same error if the output file already exists.
The output produced (once you get it to actually produce output!), is initially not the .png you are specify, but rather an EPS format file. (with a .png extension).
Chart::Gnuplot then goes looking for a convert utility (from the ImageMagick distribution), to translate that into the required .png (gif, bmp etc.)
Depending upon the output format required, it will also go looking for a couple of other utilities, ps2pdf, pdf2ps which are also not a part of the distribution. I'm not sure where they come from.

It looks like it would take some serious work (and therefore a serious need!) to get this working under windows.
