I want to have a graph that shows the average time all tickets of a specific issuetype have been unresolved in every CW. So for example in CW1 I had 3 tickets unresolved, one for 1 day, and two for 4 days. Then I need the graph to show 3 days for the average unresolved time in CW1.
I tried using the Resolution Time chart. But it seems like this one is not taking the average of all tickets since between day 1 and day 2 it somehow manages to jump between 3 days and 32 days.
Any ideas?
