Create a dynamic date filter for a feature layer using Arcade in ArcGIS Online

Summary

A dynamic date filter can be applied to a feature layer within a web map to filter the layer on specified dates. The filter can be used, for example, to show all the daily updates made to the layer, instead of manually updating the filter on the web map each day.

This article highlights the workflow to create a dynamic date filter for a feature layer using a custom Arcade expression.

Procedure

1. In ArcGIS Online Map Viewer, on the Contents (dark) toolbar on the left of the page, click Layers.
2. Expand the hosted feature layer and select the feature to open the Properties pane.
3. On the Settings (light) toolbar, click Styles.

4. In the Styles pane, click Expression.

5. In the Arcade expression editor window, under Expression, insert the following expression:

Expects($feature, 'Date_Field_Name')

var time = -1
var units = 'days'  //milliseconds, seconds, minutes, hours, days, months, years
var dateField = "Date_Field_Name"

var pastDate = DateAdd(Date(), time, units)
if($feature[dateField] > pastDate)
{
    return 'Open'
}

Note:
Change the first three variables to any desired value. The supported units are milliseconds, seconds, minutes, hours, days, months, and years. The dateField variable is the date field queried.

6. Click OK.
7. Set a refresh interval for the feature to update dynamically. Refer to ArcGIS Online: Set refresh interval (Map Viewer) for instructions.

The map shows the custom dynamic date filter created for the feature layer.
