Burndown charts

Bumping this. Would be great to have a burndown chart or cumulative flow chart for Kanban boards. It looks like this has been requested for ages. When will it be in the pipeline?

+1 to feature request for a burndown chart as a dashboard widget.

+1 for this and would like a burnup chart as well.

I was able to hack a burnup for my needs by using a Date Created and a Date Complete column. Using a fresh duplicate of the board (I know) I was able to add the board twice to a dashboard and used the Date Created for one copy and Date Complete for the other. If I could just add the same board to a dashboard twice I would be able to do this without all the hassle.
