Hi @Terry ,
You can create Age interval dimension for this use case. See in in eazyBI documentation how to import Age interval: Jira Issues Import - eazyBI for Jira
To define one-week intervals, you need to use this in the configuration 0,8,15,22,29
See more on how to define different intervals here: Interval dimensions - eazyBI
Also, there is an example report from the eazyBI demo that uses age interval: Unresolved issues by age interval and priority - eazyBI for Jira
best,
