transparent lines and points

[Mojca M. <moj...@gm...>]

Hello,

there are dozens of demos using transparent objects in gnuplot, but I
don't remember seing support for drawing transparent lines. Is that
possible?

I have the same question regarding transparent points, but I guess
that drawing "with circles" might be the easiest choice in that case
(if transparent points are not supported).

Thank you,
    Mojca
