Add an entity type

To add an entity type to a link chart, complete the following steps:

  1. Click the Entity Type button to add your first entity type.

    The Add new entities from layer dialog box appears.

  2. Choose a layer from the Choose Layer drop-down menu.
  3. Choose a field from the Choose field for entities drop-down list.

    This field should represent a list of entities that will be rendered by default as individual nodes in the chart. This field can be any valid String, Date, Double, GUID, GlobalID, Integer, OID, Single, SmallInteger, or XML field.

  4. Type a name for your entity type in the Enter name for the entities text box.

    This name will help distinguish between entity types that may be from the same layer.

  5. Optionally, check the Visually Collapse Duplicate Entities check box.

    If checked, all duplicate entries in the field specified in Choose field for entities will render as a single node.

  6. Click OK to load the entities into the link chart.

    Individual entity types are loaded into the link chart and displayed as nodes. The symbology of the nodes is the same as the symbology of the source layer. To change the symbology, select the entity type in the Contents pane and click the Symbology button on the Link Chart Diagram tab or right-click the entity type and click Symbology.


    Edits made to the link chart data sources, such as adding new features, updating feature attributes, or deleting features, are not automatically synced to the link chart; you must click the Refresh button in the link chart view pane to sync them. The time the link chart was last synced is displayed in the Current as of label in the link chart view pane.

  7. Optionally, click the Entity Type button and repeat the steps above to add more node sets.

    You can add an indefinite number of entity types, as long as they are all sourced from layers in the same map. For example, you can have a link chart that contains entity types from multiple layers and entity types from the same layer with different fields defining the entity field.

  8. Optionally, edit the parameters of an existing entity type.
    1. Right-click the entity type in the Contents pane and click Properties.

      The Entites Properties dialog box appears.

    2. Make your changes and click OK.

      The chart updates.

Change the node symbology

By default, node sets use the same symbology as the map layer from which they were created. To change the symbology of a node set, complete the following steps:


When link charts draw at small scales, nodes are displayed using a simple symbol with a default color. To adjust the default color, enable the Override Overview Node Symbol Color, and select a color from the color picker.

  1. Select the entity type in the Contents pane and click the Symbology button on the Link Chart Diagram tab.

    The Symbology pane appears.

  2. In the drop-down menu, choose Single Symbology.
  3. To go back to using map symbology, choose Map Symbology.
  4. Click the Symbol button to activate the symbol gallery, and choose a symbol for the nodes .
  5. The symbol gallery displays all point symbols from all the styles in a project. To use custom symbology for a node set, add those symbols to a new style in the project.
  6. Click the symbol again, click the Properties tab, and edit the symbol properties.
  7. Optionally, edit the label properties.
    1. Right-click the entity type in the Contents pane and click Properties.

      The Entities Properties dialog box appears.

    2. Change any of the following properties:
      • Name
      • Non-Spatial Entity
      • Label Field
  8. Optionally, turn off the node frame in the Node Frame section of the Symbology pane.

    By default, the node frame is displayed for all nodes.
