问题 I want to have the 'start middle end' label appear at the top of my graph But it seems to default to the bottom no matter where I put the code. Is it possible? digraph G { rankdir=LR; {node [shape=plaintext, fontsize=16]; "Start"->"Middle"->"End"[style=invis]; } node [shape=box]; { rank=same "Start";a; } { rank=same "Middle";b;d; } { rank=same "End";c;e; } "a"->"b"->"c"; "d"->"e"; } 回答1: This works for me. digraph G { rankdir=LR; { node [shape=box]; blank [style=invisible] blank -> d [style

问题 I have used the following code to have a graph in main page of doxygen /*! \mainpage \dot digraph example{ node[shape=record, fontname=Helvetica, fontsize=10]; b [label="class cell_deinterleaver" URL= "\ref Cell_deinterleaver" ]; c [label="class freq_deinterleaver" URL= "\ref freq_deinterleaver" ]; b -> c [arrowhead= "open", style = "dashed"]; } \endot */ But I get the following message "reached end of file while inside a dot block! The command that should end the block seems to be missing!"

问题 I used graphviz based on the recommendation given to me by many people but I ran into a problem. I want to write a dot in ocaml using the Format.module and I have a record with five fields that define an automaton including the transitions which are represented by a list of int*char*int and final states which are represented by an int list. The first field is the initial state which is one int . I also defined a function member that takes a parameter and tests if it is a member of a given

问题 How to set the graph to try to fill the area allocated to it? With an increase in the number of nodes, it simply decreases in size, but also remains in one line, although the vertical size (40) allows placement down. If you remove the rankdir, then it places vertically, but also in one line. digraph "test_graph"{ rankdir = LR; bgcolor = whitesmoke; graph [size = "15, 40"]; node [shape = circle, style = filled, margin = 0, fontsize = 14, color = sandybrown]; edge [fontsize = 10, arrowhead =

问题 I have a dot file generated by a software called egypt. The dot file contains many nodes and edges. If I use this dot file to draw a picture, it is very hard see the picture clearly as there are too many nodes. And what I need is only a subgraph starting from a node, and I don't need the whole picture. Is there any way to draw a subgraph from a specified node (such as start_node) using this dot file? 来源： https://stackoverflow.com/questions/46462155/how-to-extract-a-subgraph-from-a-dot-file

问题 I have a java program and i am parsing a json file. Because there are some dependencies between the json objects (they are procedures that must be executed so some of them depends on others). I want to make a graph so i can represent this. Is there any known way? I tryed mxgraph (jgraph) but i cannot make the representation. Here is a simple json format { "blueprint": { "1" : { "depends" : null }, "2" : { "depends" : "1" }, "3" : { "depends" : { "2" , "1"} }, } } 来源： https://stackoverflow.com

问题 In my dot file stdin_in -> file_out [label=<<font color="blue">tee >/dev/null</font>>]; tee >/dev/null is supposed to be the text of the label, but it contains > which is a special character, so dot complains about it. What shall I do instead? Thanks. 回答1: Put the text in quotation marks; changing the line to stdin_in -> file_out[ label = "tee > /dev/null" fontcolor = "blue" ]; produces the desired result: 来源： https://stackoverflow.com/questions/53421641/how-shall-escape-in-an-edge-label

问题 I use graphviz to draw a diagram. The placement of the nodes are not ideal. I would like the six nodes to be roughly placed in a 2 by 3 table: file_in stdin_in string_in file_out stdout_out variable_out I have tried to add weights to some edges but still fails to move the nodes into such a table. See my dot program below. Thanks. digraph G { /* directly betw inputs */ node [color=black] string_in -> stdin_in [label="redirection"]; file_in -> stdin_in [label="redirection"]; stdin_in -> file_in

问题 I have following tree: digraph G { subgraph cluster0{ 37[label="+"]; 42[label="a"]; 44[label="b"]; 47[label="*"]; 46[label="c"]; 49[label="d"]; 51[label="e"]; 53[label="f"]; 55[label="g"]; 57[label="h"]; 61[label="*"]; 60[label="i"]; 63[label="j"]; 37 -> 42[label="c"]; 37 -> 44[label="c"]; 37 -> 47[label="c"]; 37 -> 61[label="c"]; 42 -> 37[label="p"]; 44 -> 37[label="p"]; 47 -> 37[label="p"]; 47 -> 46[label="c"]; 47 -> 49[label="c"]; 47 -> 51[label="c"]; 47 -> 53[label="c"]; 47 -> 55[label="c

问题 I have this Graphviz graph: digraph { rankdir="LR"; overlap = true; Node[shape=record, height="0.4", width="0.4"]; Edge[dir=none]; A B C D E F G H I A -> B -> C D -> E -> F G -> H -> I Edge[constraint=false] A -> D -> G subgraph clusterX { A B } subgraph clusterY { E H F I } } which produces this output: I would have expected the length of the edge between A and D to be minimised so that the nodes would be arranged as: A B C D E F G H I rather than D E F G H I A B C This works as expected if
