In early September we expanded sumUp for Jira Cloud by the Worklogs Gadget Feature. The Update 3.1.0 adds this feature to the server version of sumUp for Jira as well.
The axis values can be configured freely. This in turn makes it easy to view, for example, which employee has logged his work on which specific task with which priority. The JQL Parameter helps to determine the set of the issues in which worklogs will be searched.
