How much did it all cost? What is the total estimate for the sprint? When were these issues resolved? Often, you want to know the total values, not just the values of each element contributing to the value.
Numeric fields in Panorama are summed simply. You can see the total value of fields for all the issues which are nested under a directory or under their parent issue. The screenshot below shows how easy it is to get a sum of the total story points in a Jira epic or directory.
As you can see on the screenshot, the total value displayed next to directory or epic contains sum of story points of issues which are part of the directory or epic.
Panorama also displayed aggregated information about date fields. The aggregated information will include timespan.
