[Dsol-development] RE: DSOL Stat Classes

[Alexander V. <a.v...@tu...>]

Dear Francisco,

a) No, but this is very easy to create. Make a class that extends the
XYChart class in the DSOL package and override the notify method, or create
class that is based on the XYChart class from the jstats project, and create
your own notify method (also see XYSeries, which is an interesting class).
Just measuring data can done very easily with any class that implements an
EventListenerInterface. You could even subscribe it to the
TIME_CHANGED_EVENT of your simulator to poll the value(s) you are intersted
in, or using a more intelligent event that notifies the state changes you
are interested in.
b) No, but it is as easy te create as the above class.
c) Not yet -- it is not so difficult to make, and there are a few public
domain classes that you could incorporate in DSOL, or write it yourself.
This could be a nice contribution to the dsol project.

I copied the dsol development list on the e-mail, as there might be someone
who already created more extensive statisctics packages (Niels?).

Kind regards,
Alexander.
