Enable and configure clustering


You need the following account and license types to use this workflow:

  • Microsoft license—You need a Microsoft 365 license, role Contributor or higher, to save maps that have been styled with clustering.
  • ArcGIS account type—Standard users can perform the functions of this workflow; you do not need to sign in.

You can apply clustering while working with maps in ArcGIS for Microsoft 365. Clustering is an ArcGIS for Microsoft 365 function that places point features that are within a certain distance of one another into a single symbol.

See Clustering to learn about clustering data points.

When sharing a layer to ArcGIS, clustering is turned off. To share the clusters, share the layer as part of a map. See Share a map to ArcGIS for more information.

Enable clustering

To enable clustering on a layer, complete the following steps:

  1. In the Layers list, click Layer options Layer options.
  2. Choose the layer to modify from the Active layer drop-down menu.
  3. Click Clustering Clustering.

    The Clustering pane appears.

  4. Turn on the Enable clustering toggle button.

    The features on the map appear in clusters with the default configuration options.

  5. Turn off the Enable clustering toggle button to turn clustering off.

    The features on the map appear as individual features.

Configure clustering

To configure clustering, complete the following steps:

  1. Ensure that clustering is enabled for the layer you want to modify.

    Once clustering is enabled, configuration options in the Clustering pane become active.

  2. To change the distance at which points are grouped in a cluster, move the Cluster radius slider to the left for a low radius size or to the right for a high radius size.
  3. To change the color of the text on the color symbols, choose a color from the Cluster text color options.

    For more color options, click Edit Edit and use the color selector. You can also specify a custom color using an RGB or hexadecimal value.

    The map automatically updates to reflect the new color settings.

  4. Click Close Close or Back Back to close the Clustering pane and display the map.
