Gmane can be used to get day by day mail traffic to all octave lists for
the last several years at least. See for example

http://gmane.org/output-rate.php?group=gmane.comp.gnu.octave.maintainers

or

http://gmane.org/output-rate.php?group=gmane.comp.gnu.octave.general

The complexity is then massaging the date string into something that can
be used for a plot, and using a suitable averaging window. I took the
time to do this on a yearly scale, and got the attached plot for 1992 to
2005. The data in in the attached script..
