Scaling Node Size or Edge Width by a Property Value

You can select a property of a category or relationship whose value will be used to scale the size of its nodes or edges, respectively.

The Node Size Scale and Edge Width Scale sliders in the Settings tab determines the basic size of all nodes and edges, respectively. Nodes and edges can then be scaled by size or width, respectively, using values of a selected property.

The property value can be accessed using the styling dialog available in legend list items. You simply select a property from a menu in the Size or Bind Width tabs. This is an easy way to set and change properties of interest. You can also go to the Project panel and Category or Relationship tab and use the Node Size or Bind Width checkboxes in the property lists there; this usually takes more time.

To scale nodes or edges by a property value using the styling dialog:

1. Go to Category or Relationship tab in the legend.

2. Click the colored dot (or line) to display its styling dialog (in this example, the Location category or OCCURED_AT relationship).

3. For a category (Location), click the Size tab and select the property to be used to scale node size (e.g. annualCrimes).

   

   For a relationship (OCCURED_AT), click the Bind Width checkbox for the relationship property (severity) to be used to scale edge widths. In the example, the width of OCCURED_AT edges is scaled according to a severity property associated with the connected Crime node.

   

To scale nodes or edges by a property value in the Project panel:

1. Go to the Project panel and Category or Relationship tab.

2. Select a category or relationship (in this example, the Episode category).

3. For a category, click the Node Size checkbox for the property to be used to scale node size (e.g. numLines).

   

   For a relationship, click the Bind Width checkbox for the relationship property. In the example below the spoke relationship includes a numLines property. Selecting it scales the width of spoke edges according to the number of lines spoken by a character.

   

Although Node Size or Bind Width checkboxes are available for any property, a property with numerical values (rather than text) produces more obvious visual results.
