Comparing two different date periods in a Qlik Chart

[AndersGS]

Hi,

I'm have a chart comparing two different date periods. My data looks like this:

Date	Web CR% 2020	Web CR% 2019
2019-11-12	-	3,4%
2019-11-13	-	3,2%
2019-11-14	-	2,1%
2019-11-15	-	2,2%
2019-11-16	-	1,3%
2019-11-17	-	1,6%
2019-11-18	-	2,7%
2020-11-17	3,9%	-
2020-11-18	3,5%	-

The first day of this year is 2020-11-17 and it should compare to the first day of last year, 2019-11-12
and onward. My goal is like below (made in Excel)

this is the (obvious) result in Qlik when using 'Date' as Dimension:

We are using QlikView 11.2.

Any ideas? 

Thanks,
Anders

Could a number list instead of dates be an option?
Does anyone have an idea on how to do that?
