I download the snapshot, and it works! Integrated into the GUI,
fantastic. (I mean: I can't think of any other software where a
feature idea would be implemented so rapidly.) Thank you again!
A short side note. I believe that such factorization is most useful
(in addition to boxplot, you've just implemented!) in case of
histograms and kernel density estimations, where the respective
diagrams beneath (in case of histograms) or superimposed on each other
(kernel density estimates) are very effective to visually assess
whether there is significant difference in the expected value (and
perhaps variance) of a variable between the groups. (Kind of a
graphical way to the same problem which is analytically addressed by
the two sample t-test or ANOVA.) I called it a "side note" because
this most often arises in biostatistics, psychometrics etc. as I see
(that is, more experimental applications of statistics) and not in
econometrics - so I completely understand if you decide intentionally
not to implement this in gretl, irrespectively of your free time.
Thank you again for you attention,

OK, now in CVS and snapshots you can use any discrete variable,
not just a 0/1 dummy, with gnuplot and the --dummy option.
In the same line of business I've added a --factorized option
the boxplot command, and enhanced the GUI boxplot options (e.g.,
on right-clicking a variable and selecting Boxplot).
