As I understand how this gadget works the issue must be in the 'Done' state so it can count on the chart. I don't believe this could be changed, not inside Jira at least.
Here I found some documentation about what you can do in this gadget:
My Jira Chart Board has a "Statistics Burndown Chart" view which shows my projected Point completion rate, compared with my actual point completion rate. To show on this chart as completed effort, my stories need to pass to my last milestone "Done". I want the subject chart reflect completed effort in the the workflow step before done. How do I do that?
