Re: [Gnuplot-bugs] gnuplot 4.1-cvs checkout today, 3D vectors with PDF terminal

[alessandro s. <sa...@gm...>]

for me postscript is fine or even better because of the linestyle
which are much cooler...

yet i have the feeling there could be something to be fixed in pdf
terminal... if it's not me who's doing something bad

that said,=20

small data file "file"... i'm sorry lines will be split and i have no
website where to upload it :(
i put an empty line between every two true lines, so that you can distingui=
