Dear all
1. I use the command, gnuplot as follows
gnuplot x1 x2 y1 y2 --time-series --with-lines
without any problems. What should I do if I would like to draw x1 x2
with lines but y1 y2 with points?
2. The command, gnuplot, in console can generate a plot. But it seems
not to work when I use the same gnuplot command in a script. It
responds that, for example,
wrote D:\Subdir\gpttmp01.plt
Is this normal? How can I access (open) *.plt files?
Thanks

Either use the GUI plot editor, or exploit the
{ extra gnuplot commands; }
mechanism. See gretl's command reference entry for "gnuplot".

Yes, it's normal. See the gretl command entry for "gnuplot". You
can access .plt files using a text editor or using gnuplot itself
(wgnuplot.exe in the gretl program directory).

Yes, to use GUI to plot the graph with different linetypes (as well as
different Y axes) is OK.
The gretl manual does not provide the example I need. So I visit
http://www.gnuplot.info/docs/node100.html to try the gnuplot commands.
They generally works. But I found if I use the command line in the
gretl console (for example, using the below script with djclose.gdt)
series r=ldiff(djclose)
gnuplot r djclose { plot '-' using 1:($2) axes x1y2 title "Returns
(right)" w lines, '-' using 1:($2) title "djclose (left)" w
linespoints;} --time-series
The graph comes out as expected.
However, this graph cannot be edited. That is, click on the graph
\edit, on the tab "lines" in the dialog box, there is only "line 1"
left.
It happened if the last semi-colon (after "linepoints") of the above
command is accidentally "ignored," i.e.,
gnuplot r djclose { plot '-' using 1:($2) axes x1y2 title "Returns
(right)" w lines, '-' using 1:($2) title "djclose (left)" w
linespoints} --time-series
then click on the graph and choose \edit\lines, there are now two line
as normal, but the linetypes setting were gone. I think the second
command without the semicolon should be incorrect. Is this a problem
in gnuplot?

However, this graph cannot be edited...
The GUI graph editor in gretl is designed to work with graphs that
are automatically generated by gretl itself. It does not pretend
to be able to handle all possible syntactically valid gnuplot
files.
If you want to customize a plot in a way that is not supported in
the GUI graph editor, you are advised to follow the suggestions in
the Gretl User's Guide. That is:
* Generate a plot in the GUI. Click and "save to session as
icon".
* Go to View/Icon view and locate the icon representing your
graph.
* Right-click on the icon and select "Edit plot commands".
Now you can do what you want with the plot specification, and send
the result directly to gnuplot with the "Execute" icon.
Allin.
