BackLog table form Jira tickets in DAX

[Aldis]

Hi,

The problem - I have list of Jira tickets. For each ticket I have a CreationDate and ResolationaDate. For thouse, who are still opne - ResolutionDate is empty.

If II count amout of Open tickets, I got My backlog.

The target - I need to create a teble, where I can calculate backlog size for each day in past.

That mean - I need to generat teble with dates, where I have this:

01,01,2023 - 15 tickets

02,01,2023 - 12 tickets

03,01,2023 - 16 tickets

......

and so on.

I need  to create virtual DAX table based on tickets CreationDate and Resolutiond date, and count maching tickets for Each day.

I have tryed - Summary, Summarytable, CrosJoin funcion... no succsess.

Can someone help me to show the right direction?

For date table - I use Calendar table
