SpringStiffness Method

Returns the stiffness of the spring representing the ForceDirectedEdge link. The to and from nodes of link L are acted upon by a force of magnitude SpringStiffness(L) * (GetNodeDistance(L.from, L.to) - SpringLength(L)).

Syntax

protected virtual double SpringStiffness( 
   ForceDirectedEdge e
)

Parameters

e

Return Value

Returns the stiffness of the spring representing link, normally the value of DefaultSpringStiffness, unless the value of ForceDirectedEdge.Stiffness had already been set, in which case it just returns that value.

Remarks

Very small positive numbers are normal. Values larger than that tend to cause "jittery" behavior that makes it hard or impossible to settle down, since no stable state can be found.
