基本范例  (5)

默认情况下，规则是有向边：

Wolfram Language code: Graph[{1 -> 2, 2 -> 3, 3 -> 1}]

指定无向边：

Wolfram Language code: Graph[{1 -> 2, 2 -> 3, 3 -> 1}, DirectedEdges -> False]

获得具有有向边的一个 CycleGraph：

Wolfram Language code: CycleGraph[6, DirectedEdges -> True]

从一个对称邻接矩阵创建一个有向图：

Wolfram Language code: AdjacencyGraph[(| | | | | - | - | - | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 0 |), DirectedEdges -> True]

显示边界为按 GraphPlot 的箭头：

Wolfram Language code: GraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 4 -> 1, 2 -> 4, 4 -> 5, 4 -> 6}, DirectedEdges -> True]

显示边界为不按 LayeredGraphPlot 的箭头：

Wolfram Language code: LayeredGraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 4 -> 1, 2 -> 4, 4 -> 5, 4 -> 6}, DirectedEdges -> False]

范围  (5)

DirectedEdges 是特殊图构建器包括 PathGraph 的一个选项：

Wolfram Language code: PathGraph[Range[4], DirectedEdges -> True]

CompleteGraph、GridGraph 和 ButterflyGraph：

Wolfram Language code: {CompleteGraph[5, DirectedEdges -> True], GridGraph[{2, 3}, DirectedEdges -> True], ButterflyGraph[2, DirectedEdges -> True]}

CycleGraph、StarGraph 和 WheelGraph：

Wolfram Language code: {CycleGraph[7, DirectedEdges -> True], StarGraph[6, DirectedEdges -> True], WheelGraph[6, DirectedEdges -> True]}

CompleteKaryTree 和 KaryTree：

Wolfram Language code: {CompleteKaryTree[3, 2, DirectedEdges -> True], KaryTree[6, 3, DirectedEdges -> True]}

DirectedEdges->True 防止 AdjacencyGraph 创建无向图：

Wolfram Language code: AdjacencyGraph[(| | | | | - | - | - | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 0 |), DirectedEdges -> True]

WeightedAdjacencyGraph：

Wolfram Language code: WeightedAdjacencyGraph[(| | | | | | - | - | - | - | | ∞ | 1 | 2 | ∞ | | 1 | ∞ | 1 | 1 | | 2 | 1 | ∞ | 3 | | ∞ | 1 | 3 | ∞ |), DirectedEdges -> True]

DirectedEdges 可用于 RandomGraph 和 UniformGraphDistribution：

Wolfram Language code: RandomGraph[UniformGraphDistribution[5, 6], DirectedEdges -> True]

BernoulliGraphDistribution：

Wolfram Language code: RandomGraph[BernoulliGraphDistribution[5, 0.6], DirectedEdges -> True]

默认情况下，边界显示为 GraphPlot 和 TreePlot 表示的线段：

Wolfram Language code: GraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 4 -> 1, 2 -> 4}]

显示边界为箭头：

Wolfram Language code: GraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 4 -> 1, 2 -> 4}, DirectedEdges -> True]

默认情况下，边界显示为 LayeredGraphPlot 表示的箭头：

Wolfram Language code: LayeredGraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 1 -> 4, 2 -> 5}]

下面将边界显示为线段：

Wolfram Language code: LayeredGraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 1 -> 4, 2 -> 5}, DirectedEdges -> False]
