We have been running our project for a few weeks and closed off a number of agile (greenhopper) issues yet this chart is showing 0 unresolved.
Our issues do not contain any time estimates but only user points. We always Resolve the issue by dragging into into the final field on the Agile Task board, though some we have closed using "Resolve Issue"
Looking around I can't find the answer but there was a similar question so if this helps: our Resolution field is set as hidden by default.
Any help would be appreciated.
