Excel Dynamic Range of Dynamic ranges

Question

It feels like the 1000 millionth question regarding dynamic ranges, but I have not found a solution to this one.

I am trying to replicate the following with a dynamic range using two formula values:

The formula is the current calendar week, but twice in order to work as X-axis values for a XY plot chart.

I was not able to replicate it. Neither with INDIRECT nor connecting the values using CONCATENATE or anything close to it.

It works the way it is shown in the picture, but it's not a dynamic range, which I need.

Answer 1

Ok, the solution to the problem is the following:

=CHOOSE({1,2},WEEKNUM(TODAY()),WEEKNUM(TODAY()))
