We use Kanban boards and are making an effort to drive improvements by using the Control Chart report.
Once we close an issue, we would prefer to have it not show on the board, so we don't map this status to any of the columns.
However, when we do this the issue does not get included in the Control Chart at all. If we move the Closed status into our 'Done' column then the issues are included but we now have lots of closed issues that we don't care about day to day polluting our board.
Scrum boards seem to handle this by only showing issues in the current sprint - what's the solution for Kanban? We currently apply a quick filter to hide the Closed issues, but this feels clunky to me
