Time animation of multiple layers

AvaFarouche

Greetings!

I have a two-fold question here, which will make my inexperience obvious. 

I created a LOT of different feature layers to show water monitoring data collected on different dates. For each location point, I needed to tie multiple pollutant attributes, and multiple date attributes, and the only way I could think to do that was to create a separate layer for each date. In retrospect, I think there must have been a better way to do that. But I'm still not sure what it would be. A one-to-many join?

Now I have WAY too many separate layers (...about 50) and it would obviously be best to display this in a timelapse animation, but it looks like that only works within one layer, not across multiple layers. I posted the project to a Web map so folks can go click the layers on and off, but with this many layers, it's clunky for agol. A timelapse would be best.

So it looks like I need to go back to the drawing board, and it looks like a one-to-many join might be the key, but I'd love pointers or suggestions from anyone with knowledge of this.

Thank you!

@AvaFarouche glad that you got going on this approach.

At the Pollutant Monitoring table, you should have its own Sample Unique ID. This allows to relate how many samples are tied to a location. The date attribute is simply another way to filter or narrow down the search. It's OK to have multiple samples for the same date; they will have different Sample Unique ID's. You can summarize total pollutant measurements for certain time period for each location. There are multiple ways to roll-up or drill down through this type of data.
