We had a story with the wrong number of story points (by an order of magnitude) and we discovered it when the sprint ended and now our velocity chart is broken because we have one gray bar that is enormous and has shrunk everything else.
Is it possible to either:
1) Edit a previous sprint's commitment values?
2) View a velocity chart without the commitment values?
Edit: It looks like the commitment values are just the story points for a given story at the moment the sprint is created.
Is it possible to edit the history of a story to change it's story points at that moment, or to delete a story point change?
