I want to plot "something.txt" w l title "mything" with the usual line
width but can I increase the width of the sample portion of lines that
follows the titles?

As a workaround you can use a "keyentry".


plot sin(x) w l lt 1 t '',keyentry w l lw 4 lt 1 t 'sin(x)'

I have:

plot 'demo.txt' w l title "example",\
'demo.txt' using 1:(2*$2) w l title "modif", keyentry w l lw 4 lt 1 title "double

but it says: line5: undefined variable: keyentry

"keyentry" is a new thing in gp5.4 (a second release candidate will
likely be out in a few days). It produces an entry in the legend
without plotting anything.

You can do the same with plotting something out of the yrange.

set yrange [0:10]
plot sin(x) w l lt 1 t'',-1 w l lt 1 lw 4 t 'sin(x)'

tested with Version 5.2 patchlevel 6

Works. It is nice that title '' provides no line skip between the useful
lines with a title when I plot several data arrays or functions. Thanks.
