Use case

When viewing feature layers that contain a large amount of data with timestamps, you may want to filter the data to only show data relevant to a specific time frame. This can help to visualize changes in the data over time and aids in making better interpretations and predictions of future trends.

How to use the sample

Switch between the available options and observe how the data is filtered.

How it works

Create a MapView with a Map, and add layers that have time-enabled data.
Set the TimeExtent of the map view using TimeExtent property of the .

Relevant API

Map
MapView
TimeExtent

Additional information

Note that time filtering is not applied until the MapView is provided with a TimeExtent. If the TimeExtent is null, no time filtering is applied and all content is rendered.
