Currently I'm leading our agile team in an iteration manager role as well as doing my regular dev work. One of the difficulties I'm facing as an IM is tracking burn-down/burn-up; not because I can't produce graphs, but because there's multiple projects that this team is working on at one time.

At present I have an excel workbook with sheets that contain a whole bunch of graphs, both at an overall team and by-project level. It's clunky and I spend more time tweaking formulas and double checking calculations than I'd really like. As such, I'm interested to know if anyone has used a tool that can effectively produce these sorts of reports, burn-downs, and predictions across multiple projects.

I've seen http://www.pivotaltracker.com/ do some nice things, and of course there's JIRA/Greenhopper, but I'm not aware of those being used to track the progress of multiple projects within one team. If anyone's got an idea of some tools, or has faced a similar problem before, I'd love to hear from you.
