We use Jira/Greenhopper for our project planning/tracking. The built-in graphs are great, but when a new issue/story is added during a project, the whole burn-down graph moves up rather than increasing the part of the graph when the issue was added.
Ideally I'd like to generate a Mike Cohn-style burndown graph, which shows a hump when new issues are added. Does anyone know of any plugins that support this, or been able to extract this data directly from the database?
