This report allows you to see the number of issues that were resolved on a specific date. This report is useful for visualizing the productivity of users draining items from a sprint or an issue queue.
To visualize the issued closed in your product's backlog over the last month, use the JQL search option, or an existing filter, to select resolved issues in your projects that correspond to your backlog. Then simply specify one of the automatic date ranges for Time Period (such as Last Month), select the break downs you wish to see with the Segment By option, and run the report.
To chart issues against an arbitrary date field, see the Issues by Date report.
