Directive properties

@ViewStyle directive

@ViewStyle directive is used for defining style properties of a general graph view: link distance, view, physics, repel force, etc. You can read more about each property in the following sections.

@ViewStyle

Here is the list of all properties that can be defined in the @ViewStyle directive, along with their expected types.

collision-radius: number

Sets the margin radius for each node from its centre. If node size is 10 and collision-radius is set to 20, it means there will be 10 spaces left around each node. No other node can be in that space.

The default collision-radius is 15.

Example:

  • collision-radius: 15 sets the margin radius for each node from its centre to 15.

repel-force: number

Sets the strength of repel force between all nodes. If positive, it adds a force that moves nodes away from each other, if negative, it moves nodes towards each other.

The default repel-force is -100.

Example:

  • repel-force: -100 sets the repel force between all nodes to -100.

link-distance: number

Sets the minimum required distance between two connected nodes from their centres.

The default link-distance is 30. If node sizes are 20 and link distance is 30, nodes might overlap because the minimum distance from one node centre to another is 20 + 20 = 40.

Example:

  • link-distance: 30 sets the minimum required distance to 30.

physics-enabled: boolean

Enables or disables physics which is a real-time simulation for graph node positions. When physics is enabled, the graph is not static anymore.

Examples:

  • physics-enabled: True enables the physics.
  • physics-enabled: Greater(NodeCount(graph), 100) enables the physics for graphs with more than 100 nodes.

background-color: Color

Sets the background color of the canvas.

Examples:

  • background-color: #DDDDDD sets the background color of the canvas to light gray.
  • background-color: black sets the background color of the canvas to black.

view: string: "default" | "map"

Sets the current graph view that can be either "default" or "map". The "default" view is a graph visualization on a blank background. The "map" view is a graph visualization with a map as a background where each node needs to provide latitude and longitude to be positioned on the map.

The default view is "default".

Examples:

  • view: "default" sets the view to the default view.
  • view: "map" sets the view to the map view that will be shown only if at least one node has required geo information: latitude and longitude.

@ViewStyle.Map directive

@ViewStyle.Map directive is a subset of @ViewStyle because it defines additional style properties for a graph view when there is a map background. Style properties of the @ViewStyle.Map directive are used to style the background map.

@ViewStyle.Map

Here is the list of all properties that can be defined in the @ViewStyle.Map directive, along with their expected types.

tile-layer: string: "detailed" | "light" | "dark" | "basic" | "satellite"

Sets the map tile for the map background. The default map tile is "light".

Examples:

  • tile-layer: "dark" sets the map tile to be type "dark".

@EdgeStyle

Here is the list of all properties that can be defined in the @EdgeStyle directive, along with their expected types.
