Drillable Heatmap Chart Description

This is the Need4Viz Wiki page for the Drillable Heatmap Chart.

Updated for N4V 2025.2.10

• Drillable heatmap based on a hierarchy of 1 or 2 levels of dimensions on 2 axes.
  
• 1 measure defines the color of the area representing the dimension at the level of hierarchy displayed.
• In case of multi levels, corresponding axes can be drilled.

• Dimension X axis : Dimension for the first level of the X axis of the heatmap. An optional second level dimension can be set.
• Dimension Y axis : Dimension for the first level of the Y axis of the heatmap. An optional second level dimension can be set.

• Measure : Measure for the tile coloration

• 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.
• Drilldown is also available on X & Y axis if 2 levels are set on these axes.

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.
