Hello!
We are currently using the same project in Jira for different initiatives so we basically have many sprints running in parallel and on the same board. Some of them would like to use a different option other than Story Points (for instance, Issue Count) for estimation (which is reflected in your burn-down). However, the way a board is set up now is that the option you select under the Board Configuration will be set to sprints all across that project so we can't configure a different option for any of the existing sprints.
One of our use cases is that sometimes we only address bugs in our sprint and we don't story-point them, so in that case, we need a burndown chart that shows the burndown based on issue count instead of story-points. But unfortunately, if we change that on the board config it will affect all the other sprints.
I don't think there's a way around this but thought I'd ask.
Thanks!
