GoXam for WPF v3
SpringLength Method
Northwoods.GoXam.Layout Namespace > ForceDirectedLayout Class : SpringLength Method
Returns the length of the spring representing the ForceDirectedEdge link. The to and from nodes of a link L are acted upon by a force of magnitude SpringStiffness(L) * (GetNodeDistance(L.from, L.to) - SpringLength(L)).
Syntax
protected virtual double SpringLength( 
   ForceDirectedEdge e
)

Parameters

e

Return Value

Returns the length of the spring representing link, normally the value of DefaultSpringLength, unless the value of ForceDirectedEdge.Length had already been set, in which case it just returns that value.
Remarks
If your nodes are large, you may need to increase this value, so that many nodes aren't forced to be packed in close to each other.
