How do I show change the Resolution time Report to group by severity?

[Jon Hopper]

Jira has a built-in report - Resolution time.

For the Jira reports - How do I see what filter it is running?   

I'd like to change the report to show Resolution time by Severity... Anyone know how?

Thanks

It uses whatever filter you tell it to when you configure the report before running it.

You won't be able to change it to look at severity or anything else.  The report is intended to tell us how long things are taking to get resolved.  Running it against severity would be nonsense.
