How to compare two data sets from 2 excel files each representing a different year in power bi?

For example: One excel file from 2023 has types of buildings(tall, short)

another excel file from 2024 has types of buildings(tall, short)

how to display them on one visual types of buildings from 2023 and 2024?

[CoreyP · Accepted solution]

Create a date dimension table and establish a relationship to the date column in each dataset. If the datasets do not have a date column already, create one.

must both relationship from the date table to the data set be active? or one active and the other inactive?

[CoreyP]

They should both be active.
