NSpringLayout Class

In This Topic

The NSpringLayout class represents a force directed layout, which simulates a physical system with spring and electical forces.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
<System.ComponentModel.TypeConverterAttribute(System.ComponentModel.ExpandableObjectConverter)>
Public Class NSpringLayout 
   Inherits NForceDirectedLayout
   Implements Nevron.Diagram.INMeasurements, Nevron.Diagram.INMeasurementUnit, Nevron.Diagram.INResolution, Nevron.Dom.INAttribute, Nevron.Dom.INHistoryCallback, Nevron.INReferenceHolder, Nevron.INReferenceProvider

'Usage
 
Dim instance As NSpringLayout

[System.ComponentModel.TypeConverter(System.ComponentModel.ExpandableObjectConverter)]
public class NSpringLayout : NForceDirectedLayout, Nevron.Diagram.INMeasurements, Nevron.Diagram.INMeasurementUnit, Nevron.Diagram.INResolution, Nevron.Dom.INAttribute, Nevron.Dom.INHistoryCallback, Nevron.INReferenceHolder, Nevron.INReferenceProvider

Remarks

The spring layout represents a classical implementation of a force directed layout, with spring and electicral forces. It allows for many per vertex and per edge settings, which can seamlessly reflect the nature of the graph.

Graph vertices are threated as ellectically charged particles, which repel each other. The electical force aims to ensure that vertices should not be close together. The parameters of the electrical force are controlled by an instance of the NElectricalForce class, accessible from the ElectricalForce property.

Graph edges are threated as springs. Springs aim to ensure that the distance between adjacent vertices is approximately equal to the spring length. The parameters of the spring force are controlled by an instance of the NSpringForce class, accessible from the SpringForce property.
