We have a TFS 2010 project (MSF Agile v5.0 template) project, the SSRS reports for burndown allow us to specify start and end dates for the current iteration, but the project portals excel charts parts for burndown do not seem to have that option anywhere I can find it.
Can anyone explain how I can configure the portal's excel burndown chart to have the begin and end dates I want rather than the defaults?
