Question

我想要实现a）垂直边缘标签或b）水平延伸树，以便在单个A4页面上拟合此图形。我该怎么做？

digraph g {
node[shape=point]
root -> 1 [label = "abcdefghijklmnopqrstuvwxyz$"]
root -> 2 [label = "bcdefghijklmnopqrstuvwxyz$"]
root -> 3 [label = "cdefghijklmnopqrstuvwxyz$"]
root -> 4 [label = "defghijklmnopqrstuvwxyz$"]
root -> 5 [label = "efghijklmnopqrstuvwxyz$"]
root -> 6 [label = "fghijklmnopqrstuvwxyz$"]
root -> 7 [label = "ghijklmnopqrstuvwxyz$"]
root -> 8 [label = "hijklmnopqrstuvwxyz$"]
root -> 9 [label = "ijklmnopqrstuvwxyz$"]
root -> 10 [label = "jklmnopqrstuvwxyz$"]
root -> 11 [label = "klmnopqrstuvwxyz$"]
root -> 12 [label = "lmnopqrstuvwxyz$"]
root -> 13 [label = "mnopqrstuvwxyz$"]
root -> 14 [label = "nopqrstuvwxyz$"]
root -> 15 [label = "opqrstuvwxyz$"]
root -> 16 [label = "pqrstuvwxyz$"]
root -> 17 [label = "qrstuvwxyz$"]
root -> 18 [label = "rstuvwxyz$"]
root -> 19 [label = "stuvwxyz$"]
root -> 20 [label = "tuvwxyz$"]
root -> 21 [label = "uvwxyz$"]
root -> 22 [label = "vwxyz$"]
root -> 23 [label = "wxyz$"]
root -> 24 [label = "xyz$"]
root -> 25 [label = "yz$"]
root -> 26 [label = "z$"]
root -> 27 [label = "$"]

}

Answer 1

rankdir = LR可以让你把它放在一个页面上

digraph g {
graph[rankdir=LR]
node[shape=point]
root -> 1 [label = "abcdefghijklmnopqrstuvwxyz$"]
root -> 2 [label = "bcdefghijklmnopqrstuvwxyz$"]
...
}

Answer 2

我刚刚在网上发现的一个解决方法是用'\ n'分隔每个字符（例如换行符）。它不漂亮，但它基本上实现了垂直边缘标签：

例如：

root -> 1 [label = "f\ng\nh\ni\nj\nk\nl\nm\nn\no\np\nq\nr\ns\nt\nu\nv\nw\nx\ny\nz\n$"]

Answer 3

一种可能性是使用unflatten实用程序。

例如：

unflatten -l 8 yourdotfile.gv | dot | neato -s -n2 -Tpng -o result.png

结果图表不像以前那么宽。

使Graphviz边标签垂直（或使树水平延伸）
