This message is in response to a posting Sven Schreiber made to
the gretl-devel list (see
http://lists.wfu.edu/pipermail/gretl-devel/2009-September/thread.html
and the thread titled "plot export problems with pdf"), but I
thought the reply might be of general interest.
Now (in CVS and Windows snapshot) when you choose Save as EPS or
Save as PDF from gretl's graph popup menu you get a dialog box
which lets you fine-tune the appearance of the graph for the
particular output type. You can select the size, the font,
color/monochrome, and a "line width factor". A line width factor
of 1.0 leaves the lines at their default width for the given
output type, but if you think this looks too fine you can make
them heavier by specifying a higher value.
You also have a preview button which lets you see the graph on
screen in its target format. For this to work for EPS you'll
obviously need to have a PostScript viewer in place. (On Linux
there's Preferences item to identify the program you want; on
Windows and OS X we leave that to the operating system.)
Also, if you actually save a graph via this dialog, the dialog
settings will be remembered (i.e. if you go to save a second graph
the settings from the first will appear as the defaults.)
