[Gretl-devel] Data labels in scatterplots

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. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
