Public Class ExpandedClusterSpiralLayout
    Inherits ExpandedClusterLayoutBase

Remarks

A user can hover over a cluster to expand it. For more information on how expand clusters, refer to the following section: Allow Users to Expand Clusters.

When the cluster is expanded, nested items that form this cluster are positioned on the map according to a specified layout. To use a spiral layout, assign an ExpandedClusterSpiralLayout object to the InteractiveClusterModeBase.ExpandedClusterLayout property.

Use the StartRadius property to specify the radius of a spiral’s inner circle.

You can override the GetLocation method to obtain the location of a specific item after the parent cluster is expanded.

Example

The following code allows users to expand clusters. The ExpandedClusterSpiralLayout applies to clustered items:

MouseHoverInteractiveClusterMode interactiveMode = new MouseHoverInteractiveClusterMode();
interactiveMode.ExpandedClusterLayout = new ExpandedClusterSpiralLayout();
map.InteractiveClusterMode = interactiveMode;

Dim interactiveMode As MouseHoverInteractiveClusterMode = New MouseHoverInteractiveClusterMode()
interactiveMode.ExpandedClusterLayout = New ExpandedClusterSpiralLayout()
map.InteractiveClusterMode = interactiveMode
