我正在使用 Graphviz 创建一个带有类似 HTML 标签的节点的图形。我的点文件：

digraph 0 {
   center = true
   charset = "UTF-8"
   overlap = false
   splines = true
   landscape = false
   id = "0"
   label = "Graph Example"
   labelloc = "t"

node [shape = none width = 0 height = 0 margin = 0 fontcolor = blue ]

0 [ label = <
    <TABLE BORDER = "0" CELLBORDER = "1" CELLSPACING = "0" CELLPADDING = "5" ALIGN = "CENTER" BGCOLOR = "white" COLOR = "black" >
        <TR>
            <TD PORT = "0" >Node 0</TD>
        </TR>
        <TR>

1:4:s -> 4:4:n

0:2:s -> 2:2:n
0:3:s -> 3:3:n
0:6:s -> 6:6:n

4:6:s -> 6:6:n
3:5:s -> 5:5:n
0:4:s -> 4:4:n

edge [color = red constraint = false ]

1:1 -> 4:4
1:1 -> 3:3

}

我正在使用端口来定义节点上我想与其他节点连接的位置。附上dot生成的图片。

我想将边缘绘制为折线而不是曲线。我试图修改图形的 splines 属性，但它不起作用，实际上从 graphviz 文档中我发现了这一点：“值 ortho 指定边缘应路由为轴对齐段的折线。目前，路由不处理端口或以点表示的边缘标签。”

您能否帮助找到使用端口的折线（或更好看的边缘）的解决方案？

谢谢。

只需更改：

splines = true

至

splines = polyline

为我做了伎俩

结果
