GraphViz 中的定位和箭头方向

Question

我正在尝试使用 GraphViz 将一些非常古老的文档迁移到我们的内部 wiki。

我不习惯 Dot 语言，需要一些帮助

参见以下示例：

我做了很多实验，但到目前为止我做的最好的是：

digraph CentralPmr {  
  fontname="Helvetica";
  shape=box;
  node[shape=box];
  graph [splines=ortho]

  sg  [label="TTD storage group for\nthe logged values"]
  vc  [label="Value catalogue"]
  tc1 [label="Time catalogoue (1)"]
  tc2 [label="Time catalogoue (2)"]
  sv_ [shape=point,width=0.01,height=0.01];
  sv  [label=""]
  ie  [shape=none, label="Initiating event"]
  c1  [shape=none, label="The set of values, defined\nby the value catalogue, which\nare freezed out of the TTD\nstorage group of the actual log."]
  c2  [shape=none, label="Time catalogue defining\nat what time around the\ninitiating event values\nshould be collected."]
  sgf [shape=record, label="{<f0> 1|2|3|4|..}|{ | | | | }"]

  sg  -> sv_ [penwidth=4, dir=none];
  sv_ -> sv -> tc2 [penwidth=4]
  sv  -> sgf:f0 [penwidth=4]
  {vc, tc1}  -> sg
  c1  -> sv [style=dashed, arrowhead="open"];

  {rank=min;  ie} 
  {rank=same; sg c1}
  {rank=same; vc sgf}
  {rank=max;  rc2}
}

不必与来源完全相同，但我希望它易于理解。

问题是：

如何在 "Value catalogue" 和 "Time catalogue (1)" 之间放置文本？
[编辑] 如何强制指向 "TTD storage group for PMR-freezed value" 的箭头从侧面而不是从上方？它是内存区域的虚拟化，箭头指向特定的内存post。在其他图像中，它可以指向内存区域中的其他内存post（例如2、3、4..）。
是否可以从 "Initiating event" 创建锯齿线？
如何在底部放置解释不同类型线条的图例？
[edit] 如何在 "TTD storage group for PMR-freezed values" 的上方、下方和右侧添加评论？
[编辑] 如何使 "TTD storage group for PMR-freezed value" 更宽？

Answer 1

不确定我是否完全理解你想要的，但低于我的理解。这只是第一次尝试，可以做更多的微调。我可能会使用类似于 HTML 的节点，其中文本和 "box" 需要更接近，特别是原始图中的 "TTD Storage Group for PMR freezed values"。

我对你问题的回答是：

如何在 "Value catalogue" 和 "Time catalogue (1)" 之间放置文本？

--- 见下文。我把它放在两个时间目录之间，和原图中一样，但是很容易移动。

如何强制指向记录的箭头从侧面而不是从上方？

--- 见下文。如果这是你的问题，你也可以使用 rankdir = LR; 来改变方向。

是否可以从 "Initiating event" 创建锯齿线？

--- 有很多方法，但需要付出很多努力（比如创建自定义形状）。据我所知，没有 "out of the box"。

如何将图例放在底部？

我不是很明白，但一般来说，当我们谈论节点时，答案会是 HTML 之类的标签。

她是我做过的：

digraph CentralPmr 
{  
    fontname="Helvetica";
    shape=box;
    node[shape=box];
    graph [splines=ortho]

    sg  [label="TTD storage group for\nthe logged values"]
    vc  [label="Value catalogue"]
    tc1 [label="Time catalogoue (1)"]
    tc2 [label="Time catalogoue (2)"]
    sv_ [shape=point,width=0.01,height=0.01];
    sv  [label="", width = 2]
    ie  [shape=none, label="Initiating event"]
    c1  [shape=none, label="The set of values, defined\nby the value catalogue, which\nare freezed out of the TTD\nstorage group of the actual log."]
    c2  [shape=none, label="Time catalogue defining\nat what time around the\ninitiating event values\nshould be collected."]
    sgf [shape=record, label="{<f0> 1|2|3|4|..}|{ | | | | }"]

    connector_1[ shape = point height = 0 width = 0 margin = 0 ]
    ie -> connector_1[ style = dotted, arrowhead = none ];
    { rank = same; connector_1 c1 }
    connector_1 -> c1[ style = invis ];
    c1 -> sv[ style = dashed, arrowhead = open ];
    connector_2[ shape = point height = 0 width = 0 margin = 0 ]
    connector_1 -> connector_2[ style = dotted ];
    { rank = same; sg connector_2 sv }
    sg -> connector_2[ minlen = 3, penwidth = 4, arrowhead = none ];
    connector_2 -> sv[ minlen = 3, penwidth = 4 ];

    vc -> tc1 -> c2 -> tc2[ style = invis, weight = 10 ];
    sg -> vc;
    sg -> tc1;
    sv -> tc2[ penwidth = 4 ];
    sv -> sgf;
}

Answer 2

这是我第一个答案的基础，编辑那个答案会造成太多混乱。我已尝试考虑您的所有需求，并且只有在您放弃 splines=ortho 要求时它才有效（我相信）。请参考我的第一个答案下面的评论。开始吧：

digraph CentralPmr {  
    fontname="Helvetica";
    shape=box;
    node[shape=box];
    // graph [splines=ortho]

    sg  [label="TTD storage group for\nthe logged values", width = 2.5]
    sv[ label="", width = 2]
    ie [ shape=none, label="Initiating event", fontsize = 18 ]
    c1 [ shape=none, label="The set of values, defined\nby the value catalogue, which\nare freezed out of the TTD\nstorage group of the actual log." ]

    sgf[shape=box, margin=0, label=<

    sg -> connector_2[ minlen = 3, penwidth = 4, arrowhead = none ];

    sg:sw -> TTD:f1:nw[ weight = 5 ];
    sg:w -> TTD:f2:w;
    sv:sw -> TTD:f3:e[ penwidth = 4 ];
    sv:sw -> sgf:f1:w[ penwidth = 4 ];

    node[ shape = plaintext ];
    leg2[ label = "Data flow" ];
    leg4[ label = "Reference" ];
    leg6[ label = "Comment" ];

    node [ shape = point height = 0 width = 0 margin = 0 ];
    leg1 leg3 leg5

    TTD:sw -> leg1[ style = invis ];

    { rank = same; leg1 leg2 leg3 leg4 leg5 leg6 }
    edge[ minlen = 2 ];
    leg1 -> leg2[ penwidth = 4 ];
    leg3 -> leg4[ style = dotted ];
    leg5 -> leg6[ style = dashed, arrowhead = open ];
}
