Treemap Chart Description

This is the Need4Viz Wiki page for the Treemap Chart.

Updated for N4V 2025.2.10

• Drillable diagram based on a hierarchy of up to 5 levels of dimensions.
  
• 1 measure defines the size of the area representing the dimension at the level of hierarchy displayed.

• Dimension 1 : Dimension for the first level of the treemap
• Dimension 2 to 5 : [Optional] Dimension for the second to fifth level of the treemap

• Measure 1 : Measure for the tile size

• Display the tooltip when you move the mouse over the points of the tiles.
• Drilldown in the sub-level when you click in a tile. To go back to the previous level, click on the button upper top of the chart.

Use the Webi native element link function to make this graph interact with other elements of the same report (native Webi tables / graphs and / or Need4Viz graphs). Element binding can be defined on all objects or individually on one of the dimensions of the graph. By default,the link is active only on the last level of drill, change the option in the extended parameter (selection) to activate the link on each level.

You can find instructions for accessing settings for Need4viz graphics: Format Custom Element.
