How to calculate variance ?

[Anonymous]

Hello, 
I have table that looks like this:

I created matrix like this:

What i really need is matrics that has Variances which is 2021-2020 and also %YoY which would be Variance/2020.
So something like this:

FiscalWeek	2020	2021	Variance	%YoY
Week-1	119	133	14	12%
Week-2	133	133	0	0%
Week-3	112	126	14	13%
Week-4	133	119	-14	-11%
Week-5	112	112	0	0%
Week-6	133	140	7	5%
Week-7	126	112	-14	-11%
Week-8	119	126	7	6%
Week-9	126	126	0	0%
Week-10	133	119	-14	-11%
Week-11	126	140	14	11%
Week-12	112	126	14	13%
Week-13	119	133	14	12%
Week-14	119	105	-14	-12%
Week-15	105	133	28	27%
Week-16	119	112	-7	-6%
Week-17	112	112	0	0%

And ultimatelly i need to be able to grab data from 2020, 2021 and %YoY and plot it on the line chart. 
Can this be done?

Hi, @Anonymous 

If you keep your data structure, then you can't get the above matrix effect, unless you pivot the year column, and then use a table to achieve such a visual effect.

Matrix:

Pivot the year column and use a table visual.
