Gantt 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 Gantt chart can be used to visualize tasks on a timeline, as well as their dependencies. The NeoDash Gantt chart views your tasks are nodes in the graph, and your relationships are dependencies between them.

To use the Sankey chart, nodes must have at least three properties on them:

  • A startDate

  • An endDate

  • A title

In addition, different types of task dependencies can be visualized. The dependency must be stored as a property on a relationship, and can be one of four values:

  • SE: The dependency is from the Start of the origin task, to the End of the next task.

  • SS: The dependency is from the Start of the origin task, to the Sstart of the next task.

  • ES: The dependency is from the End of the origin task, to the Sstart of the next task.

  • EE: The dependency is from the End of the origin task, to the End of the next task.

Examples
