Hello,
currently (the snapshot) one can modify almost anything of a plot by streaming it as
literals (including manipulation of the linetypes), which is very nice. But there are some
things which I for once always need to post-process manually:
1) The way in which the lines are plotted (i.e. dots, impulses, ...)
2) and the titles for the legend
For 1) it is at least possible to specify some options, using i.e.
"--with-lines=series1", but not all options.
Perhaps it is possible, in future, to provide an additional command to allow for literals
that are substituted into the
---------
plot \
'-' using 1:($2) XYZ
---------
part directly for XYZ? This would further reduce the necessity to post-process files.

Sorry I don't understand. Can you give an example of how you want to
write things and what your intended result is?

Hello,
sorry for the delay on my part.
At the moment one can only modify legend entries by changing the name of the series
accordingly. Furthermore, the way the data is plotted is limited to a few options and one
cannot adjust the width of the line, e.g.
A typical gnuplot line produced may look like:
plot \
'-' using 1:($2) axes x1y1 title "input__ACF_fft (left)" w lines, \
'-' using 1:($2) axes x1y2 title "input__AMDF (right)" w lines
In order to change this to, e.g.,
plot \
'-' using 1:($2) axes x1y1 title " ACF via FFT (left)" w impulses lw 3,
\
'-' using 1:($2) axes x1y2 title " AMDF (right)" w lines lw 3
One has to either save the plot as icon and manipulate the gp or save it as gp and
manipulate it there.

Actually, no: you can adjust the legend entry for a series via the
"setinfo" command. Here's a little example:
<hansl>
open data9-7
setinfo PRIME --graph-name="Prime rate"
setinfo UNEMP --graph-name="Unemployment"
gnuplot PRIME UNEMP --time-series --with-lines --output=display
</hansl>

True, you can't set specific line widths via options to gretl's
"gnuplot" or "plot" commands.
The thing is, there are tons of options in gnuplot and there are
diminishing returns to exposing these via options to gretl's commands.
Our code for driving gnuplot is already very complicated and handles a
large number of options -- see
https://sourceforge.net/p/gretl/git/ci/master/tree/lib/src/graphing.c
However, there's the --input=filename option to gnuplot which allows
you to formulate your own plot specification (you write the spec to
file, then source it using this option). That way you have complete
freedom. One item on my agenda (when I have time) is to write up some
help on this, and tweak a few commands so as to make it easier (for
example, provide an easier way to print data in the form wanted for a
gnuplot source file).

Here's a simple example of what I was talking about with the --input
option:
<hansl>
function string my_plot_file (series y1, series y2, series x)
string fname = "(a)dotdir/test.plt"
outfile "@fname" --write
print "plot '-' using 3:2 title 'fat line' w l lw 3, \
'-' using 3:2 w p pt 5 notitle"
print y1 x --byobs
print "e"
print y2 x --byobs
print "e"
outfile --close
return fname
end function
open data9-7
series x = $obsmajor + ($obsminor - 1)/4
fname = my_plot_file(PRIME, UNEMP, x)
gnuplot --input="@fname" --output=display
remove("@fname")
</hansl>

Hi Allin,
I didn't know the setinfo --graph-name option so far. It is great! And thank you very
much for the function example. That'll do!
