Note that “Status” dimension returns the current status of an issue even if “Time” dimension would be used in the report. Therefore measure “Open issues” may not give you expected results when “Status” dimension is filtered.
To display a number of issues in historical statuses over time, we recommend importing issue change history (via eazyBI import settings).
That will create some new dimensions and measures in your eazyBI JIRA issues cube.
Next, you could use measure “Issues history” together with “Time” dimension and filter your report by “Transition Status” values.
