New to Jira: How to get the Burn down chart for epic, stories & Sub-tasks

Question

Hi Team,

We are using Scrum Board.

Epic->Story->Sub-Task's

Assumption:

Sub task's efforts should roll up to story and then epic, where epic and story efforts are mentioned as 0m, in assumption if we complete the sub-task's respective stories and epics are also getting completed in parallel.

using this way i am not getting the clear burn down chart information, what we should do. need your assistance.

You could also try the Epic Report.  This shows you progress over time in a specific epic by number and story points of Stories.  So again, you'd need to track at the Story level.

A burn down chart shows you how you are doing against what you committed to at the start of the sprint.

It burns down when a Story is marked as "done" - that's what you committed to and you achieved it.  Either a story is done, or it is not, therefore estimates on sub-tasks are useless in burn-down.  If any sub-task is incomplete, you're not "done", so you have nothing to measure.

So, you need to estimate on Stories if you want to use a burn down.
