A Scrum BurnUp Chart is a specific Big Visible Chart that is used to show progress for a release or iteration. The horizontal axis represents Time and the vertical axis represents Scope. For a release burn up the horizontal axis is used to represent iterations while for an iteration burn up it is used to represent days.
Contrary to Scrum BurnDown charts, BurnUp charts allow to give more visibility to scope change as it is clearly represented as a moving line at the top of the chart.
