Trends and comparisons
Split your JQL into weeks or months by a date field and see the direction at a glance.

How periods are counted
For each period the gadget adds a date window to your query. For weeks and the Created field, the current week and the one before are:
JQL per period
(your JQL) AND created >= startOfWeek() AND created < startOfWeek(1)
(your JQL) AND created >= startOfWeek(-1) AND created < startOfWeek()Weeks follow your Jira site's first day of the week. The current period counts what has happened so far.
