Thanks for the example. It gives me the idea. Only a small correction
was needed for my gnuplot installation
Instead of the command:
"set style line .... " , the command "set linestyle ...." was necessary,
otherwise it did not work.

Well, if I knew how to do it :-). Nevertheless, I tried it the usual
way, and it seems to work ( I forget sometimes to try first the simplest
solution).

And indeed the PNG file is created. The only problem, which has nothing
to do with your package, is that in Windows, the "linewidth" command
does not appear to have effect on the window terminal and the PNG
output, but it works only for a postscript output.
