带点文字换行(graphviz) [英] Text wrapping with dot (graphviz)

问题描述

我使用下面的代码使用点(graphviz)创建图形.

I used the code below to create a graphic using dot (graphviz).

digraph
{
  node [color=Blue,shape=box]

  1.1 [label="Frequency of t exceeds upper threshold"]
  2.1 [label="t has d-mutant tiles"]
  2.2 [label="Valid"]
  3.1 [label="Frequency of t exceeds lower threshold"]
  3.2 [label="Frequency of t exceeds lower threshold"]
  4.1 [label="Insufficient evidence"]
  4.2 [label="Valid"]
  4.3 [label="t has only one d-mutant that exceeds lower threshold"]
  4.4 [label="Are there any d-mutant tiles with significantly higher frequencies?"]
  5.1 [label="Insufficient evidence"]
  node [color=Green] 5.2 [label="Correct t to t'"] node [color=Blue]
  5.3 [label="t has a d-mutant tile t' that is closer than all other d-mutant tiles and for which a corrected base has a higher quality score"]
  5.4 [label="Valid"]
  6.1 [label="Insufficient evidence"]
  6.2 [label="t' is unique"]
  7.1 [label="Insufficient evidence"]
  node [color=Green] 7.2 [label="Correct t to t'"] node [color=Blue]

  1.1 -> 2.1 [label="no"]
  1.1 -> 2.2 [label="yes"]
  2.1 -> 3.1 [label="no"]
  2.1 -> 3.2 [label="yes"]
  3.1 -> 4.1 [label="no"]
  3.1 -> 4.2 [label="yes"]
  3.2 -> 4.3 [label="no"]
  3.2 -> 4.4 [label="yes"]
  4.3 -> 5.1 [label="no"]
  4.3 -> 5.2 [label="yes"]
  4.4 -> 5.3 [label="no"]
  4.4 -> 5.4 [label="yes"]
  5.3 -> 6.1 [label="no"]
  5.3 -> 6.2 [label="yes"]
  6.2 -> 7.1 [label="no"]
  6.2 -> 7.2 [label="yes"]
}

如您所见，图形中的某些框在标签中包含很多文本.我可以插入\n字符以确保盒子不太宽，但是我想知道是否有一种方法可以设置盒子的宽度，然后让盒子标签进行硬包装.这可能吗?

As you can see, some of the boxes in the graphic have a lot of text in the label. I can insert \n characters to make sure the boxes aren't too wide, but I'm wondering if there is a way I can set the width of the boxes and then have the box labels do a hard wrap. Is this possible?

推荐答案

graphviz不支持自动换行符.您必须手动输入\ n.

graphviz doesn't support automatic line breaks. You have to put the \n in manually.

您可以为节点设置宽度和高度并将其定义为fixedsize-这将 限制节点的大小，并且仅绘制适合该节点的文本

you can set a width and a height to a node and define it as fixedsized - this will limit the size of the node and draw only as much text as fits into the node
