Background: I have an excel table with ~200 records of temporal data for 9 counties (a total of ~1800 records), and I am trying to display the change over time in an animation in ArcGIS Pro. My only spatial layer is a single shapefile with the boundaries of the 9 respective counties (9 records in total). My dilemma is that this article suggests performing a one-to-many join as a way to connect my temporal data to my spatial data, while this community discussion suggests that a one-to-many join isn't an available feature in Pro. There appears to be a solution posted in the discussion by using a query table, but I don't have a great understanding of coding, thus I am looking for another work-around to meet my deadline. If none exists, I will use this as an opportunity to dive headfirst into my introduction to coding. Is it possible to use a one-to-many relate to display the external temporal information within the boundaries of my shapefile?
