PREDICTABILITY (orange line): STORY POINTS COMMITTED and STORY POINTS AT CLOSING are compared. If they are equal, Predictability is 100%. If they are not equal, Predictability drops by the difference. (for details, see addendum)

SPRINT ISSUES ADDED (red line): The amount of stories added to sprint after the sprint start date are counted. These are disturbances, while are likely detrimental to STORY POINTS AT CLOSING.

5) When sprints from other teams are shown in your chart, this is likely because you have exchanged a story - something that was in their sprint previously and you completed, or something that was in your sprint previously that they completed. If this is the case, the best remedy is to remove the data point.
Alternatively, other team's sprints can be shown because your team or story is assigned incorrectly - this can be fixed by drilling through the item and correcting the data in Jira.

Addendum: Predictability calculation

If you complete 0 storypoints, then Predictability will be 0. However, if you complete twice the amount of storypoints of what you've planned, then Predictability will also be 0. It will be 100% when you complete as many storypoints as you planned. Make sure to only make scope changes together with PO, to optimise Business Value.
