 Dear all,
 in the past I struggled really often with gnuplot when trying to plot
 dashed and/or monochrome lines. However, this has changed since gnuplot
 5.x. Here is a simple illustration for all (which also acts as a
 personal reminder for me!): 
Thanks Artur for this excellent example. I will also add a relevant 
comment to the feature request 64 on the sourceforge tracker 
(
https://sourceforge.net/p/gretl/feature-requests/64/).
And here's a slightly modified example where both lines are dashed, and 
also it shows that you can have color as well (I think that wasn't so 
clear in previous gnuplot versions):
<hansl>
open denmark.gdt --quiet
list Lplot = LRM LRY
plot Lplot
         options with-lines time-series
         literal set linetype 1 dashtype 2
         literal set linetype 2 dashtype 2
         # literal set mono
end plot --output=display
</hansl>
Thanks,
Sven
