Diagram of work left versus time / From Wikipedia, the free encyclopedia
A burndown chart or burn down chart is a graphical representation of work left to do versus time. The outstanding work (or backlog) is often on the vertical axis, with time along the horizontal. A burn down chart is a run chart of outstanding work. It is useful for predicting when all of the work will be completed. It is often used in agile software development methodologies such as Scrum. However, burn down charts can be applied to any project containing measurable progress over time.

Outstanding work can be represented in terms of either time or story points (a sort of arbitrary unit).[1]
