Running the developer's sources, I see that the "-F:<fontsize>" option does 
pass the fontsize information to gnuplot.

Unfortunately, when I then run the result through LaTeX, I get the error below.

        ! Gnuplot Error: File `size18.clo' not found! Could not set font size.

        See the gnuplot documentation for explanation.
        Type  H <return>  for immediate help.

In this instance I tried "-F:18". Other fontsizes gave the same error. However, 
"-F:10", "-F:12", "-F:14", "-F:20" each gave the expected result.
