Sankey chart

A Sankey report generates a flow diagram from nodes and links. Note that cyclic dependencies are not supported.

Examples

Basic Sankey chart

For a Sankey chart to use the correct relationship weights, you must set a "relationship property" in the advanced settings of the report.

MATCH (p:Person)-[r:RATES]->(m:Movie)
RETURN p, r, m

Enable interactivity	on/off	on	If enabled, turn on animations when a user hovers over a node or link.
Relationship Property	Text	[value]	Name of the property with an integer value that is going to be used to determine thickness of links. Using `SANKEY_UNWEIGHTED`, this Sankey will assume every relationship with a weight of 1.

Layout	List	Horizontal	The Sankey layout direction.
Label Position	List	Inside	Controls the Sankey label position.
Label Orientation	List	Horizontal	Controls the Sankey label orientation.
Node Border Width (px)	Number	0	Controls the node border width.
Node Spacing (px)	Number	18	Controls the spacing between nodes at an identical level (px).
Node Thickness (px)	Number	18	Controls the node thickness.
Margin Left (px)	Number	24	The margin in pixels on the left side of the visualization.
Margin Right (px)	Number	24	The margin in pixels on the right side of the visualization.
Margin Top (px)	Number	24	The margin in pixels on the top side of the visualization.
Margin Bottom (px)	Number	40	The margin in pixels on the bottom side of the visualization.
