If you do not specify a value, Tableau will automatically create up to 25 clusters. Specify the number of clusters (between 2 and 50). To change the aggregation for a variable, right-click it. When you add variables, measures are aggregated using the default aggregation for the field dimensions are aggregated using ATTR, which is the standard way that Tableau aggregates dimensions. You can also drag fields out of the Variables area to remove them. Tableau displays the Clusters dialog box, where you can customize the cluster.Ĭustomize the cluster results by doing either of the following in the Clusters dialog box.ĭrag new fields from the Data pane into the Variables area of the Clusters dialog box. In some cases, marks that do not fit well into a cluster are assigned to a "Not Clustered" cluster. Tableau assigns each mark in the view to one of the clusters. If there is already a field on Color, Tableau moves that field to Detail and replaces it on Color with the clustering results. Tableau creates a Clusters group on Color, and colors the marks in your view by cluster. You can also double-click Cluster to find clusters in the view. To find clusters in a view in Tableau, follow these steps.ĭrag Cluster from the Analytics pane into the view, and drop it on in the target area in the view: Use your (Link opens in a new window) account to sign in.įor an example that demonstrates the process of creating clusters with sample data, see Example: Create clusters using World Economic Indicators data.

Cluster analysis partitions marks in the view into clusters, where the marks within each cluster are more similar to one another than they are to marks in other clusters.
