02 Methods

Name	Overloads	Summary
.ctor	1
doLayout	1	Applies the spring embedder.
repulsions	1	Calculate forces acting on nodes due to node-node repulsions...
edgeAttractions	1	Calculate forces acting on nodes due to edge attractions.
setLocation	1	Now move each node to its new location...
ForceDirectedLayout	1
Collide	1

03 Fields

Name	Overloads	Summary
forceX	1	合力累加器（双精度）。原先累加到 NodeData.force（System.Drawing.Point，X/Y 为整型），每次赋值都会被截断为整数，导致力被严重量化、布局质量差。这里改用双精度字典绕开该限制。

method .ctor #

#ctor(NetworkGraph, Size, Double, Double)

Parameters

Name	Type	Description
`g`	`NetworkGraph`	-
`size`	`Size`	-
`maxRepulsiveForceDistance`	`Double`	Repulsive forces between nodes that are further apart than this are ignored. 若未指定（传入 NaN），则依据画布尺度给出合理默认值，避免仅在 10px 内生效导致网络无法铺开。

method doLayout #

doLayout(Int32)

Applies the spring embedder.

Parameters

Name	Type	Description
`iterations`	`Int32`	-

method repulsions #

repulsions

Calculate forces acting on nodes due to node-node repulsions...

method edgeAttractions #

edgeAttractions

Calculate forces acting on nodes due to edge attractions.

method setLocation #

setLocation(Double)

Now move each node to its new location...

method ForceDirectedLayout #

ForceDirectedLayout(NetworkGraph, Size, Int32)

Parameters

Name	Type	Description
`network`	`NetworkGraph`	-

field forceX #

forceX

合力累加器（双精度）。原先累加到 NodeData.force（System.Drawing.Point，X/Y 为整型），每次赋值都会被截断为整数，导致力被严重量化、布局质量差。这里改用双精度字典绕开该限制。

method Collide #

Collide(Double)
