Hi all,
this post is mainly after a request made to me by a colleague who needed
this in class to show something to her students.
It would be nice if it was possible to tweak a few details on the labels
one can put on a scatterplot via the "Data labels" interactive facility
that we have. In detail:
(a) at present, you don't get the option if the number of points is
geraater than 250 (gui/gpt_control.c, line 89).
(b) there's no way to adjust the font size, other than saving the plot
to the session and manually tweaking the gnuplot script.
As for (a), one may think 250 is more than enough, and I agree that in
general it is. However, consider the situation when you have a big blob
of points and 2 o 3 outliers far away from the rest. Surely, it would be
nice to be able to see who these guys are.
Perhaps we could have a libset variaable to handle this, or some other
machanism.
Of course, I'm not proposing to put this in for the next release, that's
just round the corner, but it would be nice to give it some thought for
the future.
