I have developed a "Closed Sprints Trend Line Graph" using EazyBI. As time goes on and more sprints are closed it would be ideal to only have it show the last 5 completed sprints without having to manually update the graph.
How can I identify and display the last 5 closed sprints in Jira? I assume it will be use what is called a calculated member in EazyBI. Does anybody have experience in building a calculated member for this purpose?
