EdgeShapeFunction

是 Graph 和相关函数的一个选项和注释，它指定一个函数，用以生成绘制每条边所需的图形基元.

更多信息

  • EdgeShapeFunction 也被称为边路由.
  • EdgeShapeFunction 通常用于控制连接顶点的路径的视觉外观.
  • 可以使用下列选项：
  • Automatic默认的边函数
    None不绘制边
    "nfunc"一个已命名的边函数
    func一个普通边函数
    {vivj->efij,…}对于边 vivj 使用边函数 efij
    {pattiefi,…}对于与模式 patti 匹配的边使用边函数 efi
  • EdgeShapeFunction->func 指定每个边应该使用由 func[{{x1,y1},{x2,y2},…},vw] 提供的图形基元绘制，其中 {{x1,y1},{x2,y2},…} 是线段，而 vw 是边.
  • 在三维中，EdgeShapeFunction->func 指定每个顶点应使用由 func[{{x1,y1,z1},{x2,y2,z2},…},vw] 提供的图元进行渲染，其中 {{x1,y1,z1},{x2,y2,z2},…} 表示线段，而 vw 表示边.
  • 以下命名参数可用于边函数 func：
  • #Coordinates线段 {{x1,y1}, …}
    #Edge边 vw
  • 使用
    ResourceData["EdgeShapeFunction"]
    获取所有已命名边函数列表 "nfunc"：
  • 当我们在诸如 Graph 的函数中创建图时，可以使用封装 Annotation[vw,EdgeShapeFunction->f].

打开所有单元 关闭所有单元

基本范例  (4)

使用预定义的边函数绘制边：

Wolfram Language code: Graph[{12, 23, 31}, EdgeShapeFunction -> {{"HalfFilledArrow", "ArrowSize" -> .1}}]

对单条边指定一个边函数：

Wolfram Language code: Graph[{12, 23, 31}, EdgeShapeFunction -> {12 -> {"HalfFilledArrow", "ArrowSize" -> .1}}]

与一个不同的默认边函数合起来使用：

Wolfram Language code: Graph[{12, 23, 31}, EdgeShapeFunction -> {12 -> "HalfFilledArrow", "CarvedArrow"}]

使用一个 Annotation 封装来指定单个边函数：

Wolfram Language code: Graph[{Annotation[12, EdgeShapeFunction -> {"CarvedArrow", "ArrowSize" -> .1}], 23, 31}]

通过运行程序绘制边：

Wolfram Language code: ef[pts_List, e_] := Block[{s = 0.015, g = [image]}, {Arrowheads[{{s, 0.33, g}, {s, 0.67, g}}], Arrow[pts]}]
Wolfram Language code: Graph[{12, 23, 31}, EdgeShapeFunction -> ef]

范围  (10)

EdgeShapeFunction 说明  (7)

EdgeShapeFunction 可用于普通图：

Wolfram Language code: {Graph[{12, 23, 31}, EdgeShapeFunction -> "CarvedArrow"], PathGraph[Range[25], EdgeShapeFunction -> "CarvedArrow"]}

矩阵图：

Wolfram Language code: AdjacencyGraph[{{0, 1, 0}, {0, 0, 1}, {1, 0, 0}}, EdgeShapeFunction -> "CarvedArrow"]

特殊图：

Wolfram Language code: {PetersenGraph[5, 2, EdgeShapeFunction -> "CarvedArrow"], GridGraph[{3, 3}, EdgeShapeFunction -> "CarvedArrow"]}

随机图：

Wolfram Language code: RandomGraph[UniformGraphDistribution[10, 20], EdgeShapeFunction -> "CarvedArrow"]

在 Annotation 封装中使用 EdgeShapeFunction：

Wolfram Language code: Graph[{Annotation[12, EdgeShapeFunction -> "CarvedArrow"], 23, 31}]
Wolfram Language code: HighlightGraph[GridGraph[{2, 3}], Annotation[13, EdgeShapeFunction -> "CarvedArrow"]]

EdgeShapeFunction 作用于模式：

Wolfram Language code: CompleteGraph[5, EdgeShapeFunction -> {_2 -> "CarvedArrow"}]

EdgeShapeFunction 可以与 EdgeStyle 合起来使用：

Wolfram Language code: Graph[{12, 23, 31}, EdgeStyle -> Blue, EdgeShapeFunction -> (Line[#1]&)]

EdgeShapeFunction 具有比 EdgeStyle 更高的优先级：

Wolfram Language code: Graph[{12, 23, 31}, EdgeStyle -> Blue, EdgeShapeFunction -> ({Red, Line[#1]}&)]

EdgeShapeFunction 样式设置功能  (3)

获取 EdgeShapeFunction 的内置设置列表：

Wolfram Language code: ResourceData["EdgeShapeFunction"]

包含基本线条的无向边：

Wolfram Language code: Graph[{12, 23, 31}, EdgeShapeFunction -> "Line"]

边线条具有不同的标志符号：

Wolfram Language code: Table[Graph[{12, 23, 31}, EdgeShapeFunction -> {{ef, "ArrowSize" -> 0.1}}, PlotLabel -> ef], {ef, {"BoxLine", "DiamondLine", "DotLine"}}]

包含实心箭头的有向边：

Wolfram Language code: Table[Graph[{12, 23, 31}, EdgeShapeFunction -> {{ef, "ArrowSize" -> 0.1}}, PlotLabel -> ef], {ef, ResourceData["EdgeShapeFunction", "FilledArrow"]}]

线型箭头：

Wolfram Language code: Table[Graph[{12, 23, 31}, EdgeShapeFunction -> {{ef, "ArrowSize" -> 0.1}}, PlotLabel -> ef], {ef, ResourceData["EdgeShapeFunction", "UnfilledArrow"]}]

开放式箭头：

Wolfram Language code: Table[Graph[{12, 23, 31}, EdgeShapeFunction -> {{ef, "ArrowSize" -> 0.1}}, PlotLabel -> ef], {ef, ResourceData["EdgeShapeFunction", "CarvedArrow"]}]

可能存在的问题  (1)

用 Rule 表示边似乎不可行：

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

使用括号以得到正确的语法解析：

Wolfram Language code: 1 -> 2 -> "CarvedArrow"//FullForm
Wolfram Language code: (1 -> 2) -> "CarvedArrow"//FullForm
Wolfram Language code: Graph[{1 -> 2, 2 -> 3, 3 -> 1}, EdgeShapeFunction -> {(1 -> 2) -> "CarvedArrow"}]
