[Gretl-users] dashed lines

Hi, recently there has been some talk about how it would be nice if it were possible to get dashed lines in graphs, but it seems it's not so easy to implement due to some technical reasons in gnuplot. So I would like to ask the list if anybody knows any tricks how to get dashed lines anyway, presumably by hacking the gnuplot plot commands. I have tried to get the information from the gnuplot manual, but have failed so far. My preference would be using the pdf "terminal" as it seems to be called in gnuplot jargon. Any help is appreciated. thanks, sven
