I want to create JIRA Dashboard with some gadget which shows average number of hours spent on all the tickets
I have a filter created with 150 tickets.
Each ticket has different number of hours, X,Y,Z hours
I want to get average numbers of hours spent on these tickets? (X+Y+Z)/150
And I want to show this stat on jira dashboard
I tried many available gadgets on jira dashboard but it did not help
