Double Sankey Chart Description

This is the Need4Viz Wiki page for the Double Sankey Chart.

Since Need4Viz 2025.2.10

• This Sankey type diagram is a double flow diagram in which the width of the arrows is proportional to each flow represented.
• Possibility to use the functionality of linked elements on this graph.

• Dimension 1 : Dimension for the first node of each Sankey diagram
• Dimension 2 : Dimension for the second node of each Sankey diagram

• Measure 1 : Measure for the first Sankey diagram (width of the links)
• Measure 2 : Measure for the second Sankey diagram (width of the links)

• Display the related links in the two Sankeys charts when you move the mouse over a node. The corresponding values of destination nodes are calculated for this specific source node.

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.
