Any suggestion open source support ticket system

With all of the love being shown here for RT, I have a few questions
about it.  I've never actually used RT, but I used to admin a Bugzilla
server and I've used Trac a bit.  Personally, I've had good
experiences with Bugzilla.

1: does RT have any graphing capabilities?  For example, if at all
possible when I am involved with a project, I try to construct a
self-updating historical graph that shows the delta of {bugs created}
versus {bugs resolved} in a given project.  If I'm at the end of a
project and I see the count of open bugs going *up*, I know there is
trouble.

2:  does RT have the ability to answer a question like:  tell me which
bugs Joe Engineer resolved over the past week?

3:  does RT allow somebody to define milestones and to search/report
based on these?


Just wondering ; thanks!
