18 is just not supported, as stated in the gnuplot document that I
quoted in a previous letter, "To be able to use a specified font size,
a file "size<size>.clo" has to reside in the LaTeX search path. By
default, 10pt, 11pt, and 12pt are supported. If the package "extsizes"
is installed, 8pt, 9pt, 14pt, 17pt, and 20pt are added."
