I mostly use emf and postscript eps and at least for these two
the point types look completetly different (gnuplot 4.2).

I don't understand. Are you saying it is difficult to realize
the same line appearance on different terminals?
Or you are you saying you don't know a scheme of specifying
dash patterns?

I did not mean to ask for allowing users to define their own
dash patterns (although that would solve the problem as well),
but for consistency of appearance across terminals.
