Re: [Gretl-devel] point size in gnuplot

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
well.
There's now an attempt at this in git. No doubt there are bugs that
need to be beaten out of it.
As a more general remark, I've learned that with gnuplot 5 it
seems easier
(compared to gnuplot 4) to handle the data values that are given "inline" in
the gnuplot file, by specifying a named "datablock". 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 commmented on this earlier, but one more remark: I can understand
if some Linux distros are slow to update to gnuplot 5. While there's
a number of nice new features there's also a number of backward
incompatible changes -- some of which change the appearance of plots
produced by older scripts (sometimes but not always for the better)
and some of which cause older scripts to fail.
(In the current release we've upped our gnuplot requirement to
4.6.0; that's should be OK since 4.6.0 was a compatible update.)
