I am currently working with a customer that uses burndown chart to monitor their sprint and want this business requirement to be met at the close on issue
1. The chart should have the remaining estimate with a close action(post function) in place to return zero(0) for remaining estimate when an issue is closed
2. And the end of the sprint or when all the issues are close. the line for remaining values to converge to zero
Tried a solution with a graph, close to what the customer wants but the remaining displayed zero, when the issue is closed.
Please community any idea on how to go about this?
