The Sprint Burndown Chart displays the remaining effort for a given period of time. Work remaining is the Y axis and working days is the X axis. When the x and y axis coincide, the work is complete.

When tracking product development using the Burndown Chart, teams can use a Sprint Burndown Chart and a Release Burndown Chart.

The Sprint Burndown Chart consists of the following data elements:

	Product Backlog Item (PBI)
	Task
	Name
	Status (To Do, In-Progress, Closed)
	Original Estimate of time
	An array of 10 days by which work effort each day will reduce the time remaining
	Sprint Review.

The data grid is constructed as a table, which means whenever you update the table by adding or deleting rows or columns or simply changing values in the table, the graph is automatically updated.

Formulas are embedded in the chart to calculate:
    Time remaining each day after each previous work effort.
    Total work accomplished for each day.
