Graphviz 中的节点分层

发布于 2024-08-12 04:50:49 字数 495 浏览 8 评论 0原文

我正在使用 Graphviz （用 neato 编译）创建一个图表。该图包含许多重叠的节点，这非常好。然而，有一组大节点我更喜欢始终位于其他小节点之上 - 尽管我更喜欢首先在图中定义大节点（这使得它们被绘制在最底部）。

有什么办法可以强制我这样做吗？

编辑：
这是一个小例子，只是为了澄清我的意思：

graph G {
    node [style=filled,fillcolor=black];
    BigNode [fillcolor=skyblue,shape=Msquare];

    node [style=filled,fillcolor=red,shape=circle];
    edge [style=invis]
    1 -- BigNode[len=0.5];
    2 -- BigNode[len=1];
}

我希望在节点 1 上绘制 BigNode 。

I'm creating a graph using Graphviz (compiled with neato). This graph contains many overlapping nodes which is perfectly fine. However, there is a group of large nodes which I prefer to always be on top of other small nodes - even-though I prefer to define the large nodes first in the graph (which makes them get painted at the very bottom).

Any way I can force this?

Edit:
Here's a small example, just to clarify what I mean:

graph G {
    node [style=filled,fillcolor=black];
    BigNode [fillcolor=skyblue,shape=Msquare];

    node [style=filled,fillcolor=red,shape=circle];
    edge [style=invis]
    1 -- BigNode[len=0.5];
    2 -- BigNode[len=1];
}

I'd like for BigNode to be painted over node 1.

我确实找到了一种（某种）解决方案......
我发现，如果您仅将节点定义推迟到最后，即使您之前为该节点定义了边，它也会被绘制在最顶部。
我意识到这与我之前定义的内容相矛盾，但这是这种情况下唯一可能的解决方案，也是我最终不得不使用的解决方案。

在我的简短示例中，您可以这样做：

graph G {
    node[style=filled,fillcolor=black];
    // Definition of BigNode moved to the end of the file
    /*BigNode [fillcolor=skyblue,shape=Msquare];*/ 

    node[style=filled,fillcolor=red,shape=circle];
    edge[style=invis]
    1 -- BigNode[len=0.5];
    2 -- BigNode[len=1];

    // Defined after already defining edges for BigNode
    BigNode [fillcolor=skyblue,shape=Msquare];
}

在生成的图中，BigNode 绘制在节点 1 上

I did find one (sort of) solution...
I found that if you postpone only the node definition to the end, even if you defined edges for this node earlier, it will be painted top-most.
I realize this contradicts what I defined earlier, but this was the only possible solution in this case and it was the one I eventually had to use.

In my short example, you would do this:

graph G {
    node[style=filled,fillcolor=black];
    // Definition of BigNode moved to the end of the file
    /*BigNode [fillcolor=skyblue,shape=Msquare];*/ 

    node[style=filled,fillcolor=red,shape=circle];
    edge[style=invis]
    1 -- BigNode[len=0.5];
    2 -- BigNode[len=1];

    // Defined after already defining edges for BigNode
    BigNode [fillcolor=skyblue,shape=Msquare];
}

In the resulting graph, BigNode is painted over node 1
