Sankey Chart

This documentation pertains to the unsupported version of NeoDash, as part of Neo4j Labs. For users of the supported NeoDash offering, refer to NeoDash commercial.

Advanced Visualization

A Sankey visualization will generate a flow diagram from nodes and links. Beware that cyclic dependencies are not supported.

Examples

Basic Sankey Chart

For a sankey chart to use the correct relationship weights - it is mandatory to set a 'Relationship Property' in the report’s advanced settings.

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

Advanced Settings

Name	Type	Default Value	Description
Show Legend	on/off	off	If enabled, shows a legend on the bottom of the visualization.
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.
Color Scheme	List		The color scheme to use for the slices. Colors are assigned automatically (consecutively) to the different categories returned by the Cypher query.
Layout	List	horizontal	Sankey layout direction.
Label Position	List	inside	Control sankey label position.
Label Orientation	List	horizontal	Control sankey label orientation.
Node Border Width (px)	number	0	Controls Node border width.
Node Spacing (px)	number	18	Controls spacing between nodes at an identical level (px).
Node thickness (px)	number	18	Controls 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.
Auto-run query	on/off	on	when activated automatically runs the query when the report is displayed. When set to `off', the query is displayed and will need to be executed manually.
