ArcGIS Online Timeslider Feature Retention Past Start/End Time

[ckellow]

Hello, 

I am trying to work with some time-enabled data. The goal that I want to accomplish is have polygons change symbology based on their start and end times, but keep the polygons on the map the entire duration of the time slider. So if a polygon's start time has not arrived, the polygon is just a black outline until the start time where it would change to an orange coloring. Then once the end time is reached, the polygon changes to a green. 

I am asking if that is possible because from my experience working with time enabled data, the polygons will only appear if the time is between the start and end time. I understand how to use arcade to adjust symbology based on fields, but that is only helpful if the polygons can stay visual the entirety of the time.

I know that there could be a workaround where you can just duplicate your data and have multiple of the same polygon, but with different start/end times according to the status of that polygon, but I do not want to have triple the data as I will also have widgets utilizing statistically analyses in dashboards.  

Thank you for any and all help,

Cole

Hello, if you are familiar with arcade you may be able to use this option to get the result you are looking for:. There is more information on how the data has to be structured once you are in the arcade editor.   https://doc.arcgis.com/en/arcgis-online/create-maps/configure-time-mv.htm#:~:text=animation%20is%20e... 

Once you have the arcade configured, you should be able to toggle on "show features with no values" from the Styles pane for your layer and define the symbol that will show up when it is not part of the time filter. 

This workflow is still a work in progress though and make require quite a bit of refining to get exactly what you want. We are working on adding more functionality and a UI to better support it at a later release.
