I have data that shows Card Reads. I need to calculate the following and be able to use "State" as the legend
% = ([Unique card reads] / [Unique card reads in Jan. 2020]) * 100%
Basically divide every month's card reads by that value in Jan 2020, broken down by State. I tried hardcoding it and it still doesn't work but I"d like to not have it hard coded and have it in a measure.

Try :
Hope you have a DATES table connect to the fact table:
% =
DIVIDE(
[Unique card reads],
CALCULATE(
[Unique card reads],
Date[Year] = 2020,
Date[Month] = 1,
)
)

Hi @bhmiller89 ,
= CALCULATE([Unique card reads] / [Unique card reads in Jan. 2020]) * 100%), ALLEXCEPT(table, table[state]))
Thanks
