This 'using' specifier list is a bit fishy: you should enclose each 
specifier in () for extended syntax to work correctly, without
any doubts:

using 22:18:(($18>0)?$2:1/0):($18*($22-1)/(1-$18)):(0):(0)

Otherwise the ':' of your ternary expression might be confused with the 
same letter used as a separator between specifiers.

So PDFlib rejects a linewidth of zero, gnuplot doesn't.  Question is
what is setting a line width of zero here.  I don't see any obvious
candidate.  Please reduce the example to the smallest complete script 
still reproducing the effect you can create, then post that here.
