Decomposition Tree

Decomposition tree charts are a visualization used to break down a measure into its contributing factors across multiple dimensions. You can use decomposition trees to analyze hierarchical or categorical data and uncover insights by drilling down into the components that make up a total. This article explains the requirements for decomposition tree charts and details key properties, including data binding, drill-down configuration, and customization options.

Data Binding

The Data Binding tab allows you to assign data fields to decomposition tree elements and configure how the data is displayed.

  • Values – Drag a numeric field here to define the measure for each node.

    • Ellipsis menu:

      • Data Format – Opens the data format dialog to customize number formatting.

      • Display Unit – Choose how values are scaled: Auto (default), None, Thousands, Millions, Billions, or Trillions.

  • Analyze By – Drag a field here to define the dimension by which nodes are analyzed and split.

  • Tooltip – Drag one or more fields here to display additional information when a user hovers over a node.

    • Ellipsis menu: Opens a settings window with a text editor to customize the tooltip content.
