Sprint burndown is based on the completion of Subtasks or User Stories?

Question

Hi, I am looking for some information. We have two-week sprints in our project. Team commits User stories and the sub tasks underneath. When the burndown graph is rendered in the burndown chart, is it based on status of the user story OR is it based on status of the sub tasks? Please let me know that. Because my manager is saying, it's based-on User Story. But I am saying it's based on sub tasks underneath a story. Can someone throw some light on this? I don't see an option in settings to view this information.
By the way i am scrum master i have all the privileges, except JIRA board admin.

Hi @Vijay Kumar,

Indeed, the Jira's burndown chart is not based on sub-tasks; it is based on parent tasks (stories, bugs, tasks. etc).

If you want to track by sub-tasks, you will need a plugin from Atlassian Marketplace, like for example, our Great Gadgets app.

Danut.
