Liza,
AFAIK, you'll have to write your own *Statistics* object to do this. It's
not too hard—an explanation of how to do so is found in Tutorial 3
<https://cs.gmu.edu/~eclab/projects/ecj/docs/tutorials/tutorial3/>.
Personally, the first thing I often do when creating an ECJ application is
to write a Statistics object that records the genomes and fitnesses of the
entire population for every generation. That creates a ton of data, but it
makes it easy to ask whatever questions I want after a run completes.
Siggy
