% Change over user selected year columns

[ChrisIrvin]

Hi all,

First time poster! I'd appreciate any help you can give me with this question...

I need to create a dynamic matrix and line chart that shows the percentage change over selected year columns. Example below.

There are 10 years in the report and a user can select any combination of years. The selected years need not be contiguous, but are displayed in order (L to R). If a user adds more years, the table recalculates to reflect all possible % changes. If only 1 year is selected you'd see a blank table/chart. I think this means that a date table may not be appropriate as I want the calculation to work over non-contiguous years.

The result I'm looking for is exactly the same as if you used a pivot table to show % Difference From (previous).

So from this:

Category	2020	2022	2023
A	405379	338089	411576
B	263250	229064	279059
C	19864	11037	15044
D	90307	43171	125443
E	30593	17600	29115
Grand Total	809393	638961	860237

I want this:

Category	2020	2022	2023
A		-17%	22%
B		-13%	22%
C		-44%	36%
D		-52%	191%
E		-42%	65%
Grand Total		-21%	35%

And this:

Happy to provide more info.

Many thanks!

Chris.
