I don't know of a way of doing it from within gnuplot. If you want the
graph in some output format, however, I recommend writing it to EPS and
editing the PostScript by hand. From there you can use ghostscript to turn
it into whatever format you really want, if that isn't EPS.
This doesn't necessarily involve learning PostScript. You need to know
1) Somewhere, you need to replace a "stroke" with a "fill"
2) PostScript is stack-based, which means that arguments come before
3) You will almost certainly have to add a few "lineto" commands to the
list of "lineto" commands that define the curve, since you need the
corners of the graph area below the curve
