8.16 Configuring the Tree Map Portlet

A tree map allows you to visualize data significance. The size of a square provides an indication of the data element’s importance either by condition or alarm count. And, the color of each square represents its severity.

The Tree Map portlet is also available as a view from other Operations Center portlets including Alarms, Layout, Element Properties, Properties Table, Show Impacted, Root Cause, Chart Builder, Performance, and Summary. Click Actions and select Go to > Treemap from any of these portlets.
