dot

问题 I'm using dot version 2.26.3 The following .dot contents: digraph html { results [shape=none, margin=0, label=< <TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0" CELLPADDING="4"> <TR> <TD>Title</TD> </TR> <TR> <TD><I>Description.</I></TD> </TR> </TABLE> >]; } ..should produce a non-italic 'Title' and italic 'Description' when generating an SVG according to the documentation. dot -Tsvg filename.dot -o output/filename.svg However, the description is non-italic as you can see: Any idea why?

问题 I am trying to generate something similar to this: https://upload.wikimedia.org/wikipedia/commons/6/65/B-tree.svg From a btree in memory... is there any way to generate a graph like that on Graphviz, so that I can generate the *.dot file? Thanks. 回答1: Go to http://ysangkok.github.io/js-clrs-btree/btree.html and press "init simple". In the textarea you see Graphviz code for the tree shown above. The algorithm is simple, as you can see. 回答2: Yes You can use rankdir and such to set the direction

问题 Up until today, I'd been using an "ancient" version (1.4.7) of doxygen (+dot) and it typically drew graphs with a vertical orientation, e.g. .. but with a more recent one (1.8.6 as distributed via Ubuntu), the graphs seem to be horizontal, i.e. The problem with the horizontal orientation is that many of the graphs go well off the right edge of the window and so you have to do "2D" scrolling to see the data. I've looked in the doxygen web pages but couldn't see if there was an option to tell

问题 i am using this dot-Code for my Test: digraph G { edge [dir=none]; p1 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; q1 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; q2 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; q3 [shape=circle,style=filled,label="",height="0.01",width="0.01"]; {rank=same; father->p1; mother->p1}; {rank=same; q1->q2->q3}; {rank=same; son1; daughter1; daughter2}; p1->q2; q1->son1; q2->daughter1; q3->daughter2; } My

问题 I have for now a dot file generating the following graph label [A] -----------> [b] and I want to change it to something like: [A] label 1 ------> label 2 [b] Is there any way to express that in my .dot file ? I am not sure this is possible. 回答1: An edge can have a taillabel and a headlabel attribute: a -> b[headlabel="head", taillabel="tail"]; Those labels are displayed near the tail and the head of the edge. 来源： https://stackoverflow.com/questions/20149082/how-to-draw-2-labels-on-edge-in-a

问题 Using the dot directed graph language, is it possible to create subgraphs with a different rankdir? I tried the following, which didn't work. Both graphs were left to right, despite the presence of rankdir="TB" in the subgraph. digraph g { rankdir="LR"; LEFT->RIGHT; clusterrank="local"; subgraph cluster1 { rankdir="TB"; node[style=filled]; color=black; TOP->BOTTOM; } } Is there some other syntax to get a Top/Bottom and Left/Right graph in the same diagram, or is this not possible? 回答1: Seems

问题 I've been struggling with this for a while and cannot seem to find a straight answer. I'm working with compound subgraphs in graphviz and cannot seem to find the right combination of settings to force two subgraphs to align with each other. Enclosed is a simple example to show the problem... digraph g { compound=true; subgraph cluster_top { graph [color=black, label="Top", rank=min]; nodeA; nodeB; nodeC cluster_top_DUMMY [shape=point style=invis] } subgraph cluster_service { graph [color

问题 I'm having problems with edges overlapping each other. In my previous question of how to force the nodes to be in the same column, found out how to force the nodes in to one column, but this causes some other problems to appear. digraph exmp { A -> B -> C -> D -> E C -> F [constraint=false] A -> C [style="dotted", constraint=false] A -> D [style="dotted", constraint=false] B -> D [constraint=false] D -> A [style="dashed", constraint=false] C -> A [style="dashed", constraint=false] E -> F

问题 I am making some GraphViz dot graphs within my source code using Doxygen. Question: Are the graphs produced by a specific dot file guaranteed to always produce the same output? Is this the case for different computers, at different times of day, on different architectures, etc? I am considering using compass points to refine my graph and make it look nicer. I am wondering if there is any "randomness" to the initial seeding of the graph layout, or any "implementation-defined" portions to the

问题 I'm trying to generate family tree visualizations from a database using Dot/Graphviz. First results look promising, but there is one layout issue that I haven't been able to fix yet. When I use the code listed below, it will produce I'm totally happy with this. But as soon as I try to add another node between families F4/M4/M5 and F2/M2, which can be done by uncommenting the two lines in the code below, it will give me Male2 is now placed far away from Female2 and between Female4 and Male4.
