Comment 3 for bug 695371

Hi,

The bug is much more complicated than it appears. If we change the definition of what an average is during time, we should also change the other Estimator fonctions accordingly:

http://gephi.org/docs/api/org/gephi/data/attributes/api/Estimator.html

We currently don't know what is a good definition for median value and sum, because it can be very sensitive to noise at sampling/capturing a dynamic network.

The second issue is a design problem in the code: currently an estimator function can only return the same type as the values. But the average of Integers is not necessary an Integer. It is much more a feature improvement than a simple bug, so we'll work on it while runnuing the GSoC proposal on Timeline improvement.
