    ExpandedClusterSpiralLayout Class

    A layout algorithm that positions clustered items in a spiral.

    Namespace: DevExpress.XtraMap

    Assembly: DevExpress.XtraMap.v25.1.dll

    NuGet Package: DevExpress.Win.Map

    #Declaration

    public class ExpandedClusterSpiralLayout :
        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.

    ExpandedCluster - Spiral Layout

    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;
