Timeline

If you want to view vertex and edge changes over time, a timeline is required to convert a static graph into a dynamic graph. This also allows you to get dynamic analysis result.

To use this function, you need to create a dynamic graph. For details, see Creating a Dynamic Graph.

Setting a Timeline

  1. Log in to the GES console and choose Graph Management from the navigation pane on the left. On the displayed page, locate the dynamic graph and click Access in the Operation column.
  2. On the displayed graph editor page, set the following parameters in the Timeline Settings dialog box:

    The parameters set here will be synchronized to those in Community Evolution and Temporal BFS.

    • Start Time Property: Name of the start time property that is a property of the imported or created metadata. The default value is startTime. The name must be of the date, long, or int type.
    • Start: Start time of the dynamic graph. The start time must be earlier than or equal to the end time.
    • End Time Property: Name of the end time property that is a property of the imported or created metadata. The default value is endTime. The name must be of the date, long, or int type.
    • End: End time of the dynamic graph.
    • Advanced Settings: Use Default settings or Custom settings.
      • Default: Use the default settings.
      • Custom: Set the display duration of vertices and edges in the graph and the display priority of labels.
        • Vertex/Edge Display: How long the vertices and edges in an algorithm result will be displayed on the canvas. This function is supported for Temporal BFS only. The value must be a timestamp in seconds. The default value is 604800 (7 days).

        This function is used to the returned vertex and edge data that contains the start time only.

        • Label Display Priority: This parameter is available only for temporal graphs with multiple labels. For details about how to create such a graph, see Creating a Graph. You can select multiple labels. When two vertex labels have identical start and end times, the label on the left will be displayed first.

  3. Click OK.

    If you want to modify the timeline parameters, click in the lower left corner of the canvas.
