here's a very concrete feature request: In gretl's GUI window for gnuplot
there's still some space below the drop-down list for the point symbol (which
applies at least to "points" and "lines-points" styles).
IMO it would be useful to put a box there to specify the point size; for
example, a value of 0.5 would imply adding "ps 0.5" to the respective gnuplot
command line. The box could be exactly like the one for linewidth, but of
course would only be active whenever the point type selector is active as
OK, I'll take a look at that.
As a more general remark, I've learned that with gnuplot 5 it
(compared to gnuplot 4) to handle the data values that are given "inline" in
the gnuplot file, by specifying a named "datablock".
Yes, that was a feature request from me, that Ethan Merritt was good
enough to implement.
Stuff like shaded areas and so forth should be easier to achieve
from gretl's side I guess. But Debian for example switched to
gnuplot 5 less than a year ago (if I understand correctly, but could
be wrong?). I wonder what an acceptable timeframe for gretl would be
to require gnuplot 5.
I wonder too; it would be very nice to transition to the "datablock"
approach (right now we use a kinda ugly workaround). We automatically
have gnuplot 5 on Windows and OS X but I don't want to maintain two
variants of the relevant gretl code so I've been waiting for gp 5 to
become "standard" in Linux distros.
