Delta Calculation of same dimension and same measure

[CK_QLIKSENSE]

Hi everyone,

as I'm a big fan of Qlik Sense and this Community I'm trying my luck here to find a solution to my issue.

I am trying to compare the values of the same dimension with each other. The Dataset looks like this:

Dimension 1	Measure 1
A	1
B	2
C	3
D	4

Now I would like to show the Delta values of the "Measure 1" of each distinct value of the "Dimension 1". At the end, I would like to see some sort of a heatmap like this.

Delta	A	B	C	D
A	0	1	2	3
B	-1	0	1	2
C	-2	-1	0	1
D	-3	-2	-1	0

I'm kind of lost, as I'm sure there should be an easy solution for that.

Thanks a lot in advanced. Appreciate your help!
