graphviz

问题 I want to create a flowchart (similar to Visio) using Graphviz. Here is a sample digraph. digraph start_up { node [style = rounded]; node [shape = rect] start end; node [style = ""]; node [shape = diamond] "USB\nCommand\nArrived"; start -> "Initialize\nCode"; "Initialize\nCode" -> "USB\nCommand\nArrived"; "USB\nCommand\nArrived" -> "USB\nCommand\nArrived" [label="No" tailport=w headport=n]; "USB\nCommand\nArrived" -> "Has USB 3.0\nInterface Been\nSelected" [label = "Yes"]; "Has USB 3.0

问题 Is it possible to draw ASCII diagram using Graphviz? Something like that: digraph { this -> is this -> a a -> test } Gives undesired result. Instead, I would like to get similar ASCII representation: this / \ is a | test How to draw ascii diagrams from dot-files format? 回答1: If you are not perl averse, graph-easy (and the associated Graph::Easy package) can do exactly that: http://search.cpan.org/~tels/Graph-Easy/ http://search.cpan.org/~tels/Graph-Easy/bin/graph-easy On Mac you can install

问题 I have an application that uses intricate graph-like structure as a configuration. The application itself resembles a NetGraph- or netfilter firewall, thus graph nodes have types and properties (which correspond to operations) and they're interconnected with directed edges. I'd like to have an easy-to-user configuration editor for my application that provides visualization and editing for configuration as a graph. In my dream scenario, application would receive this configuration as a file in

问题 This is a follow-up question to How can I achieve strict reverse ranking of graphviz dot?, but a little easier. This graph is contrived, but demonstrates the problem: digraph nfa { A -> B B -> C C -> D D -> E A -> F F -> E } Nodes B and F are the same rank, but they are not displayed at the same rank. How can achieve this? 回答1: I used subgraphs with rank = same , and manually computed the ranks and grouped them in said subgraphs. digraph { { rank = same; A } { rank = same; B; F } { rank =

问题 For my C++ program, I need to read in a DOT file using Boost Graph, and later output another DOT file. However, I am encountering a weird error in the read-in stage which is really screwing up my program. My read-in code (Graph type is a typedef of a bidirectional Boost graph) void readGraph(Graph& graph, string filename) { boost::dynamic_properties dp(boost::ignore_other_properties); ifstream fin(filename.c_str()); boost::read_graphviz(fin, graph, dp); } Ok, so the problem is that the nodes

问题 In this graph: Rendered using Graphviz/Dot, the red edge connects two nodes, whereas the other edges connect ports inside the nodes. The nodes have HTML labels, and the TD s for the inputs and outputs have a PORT attribute. Is there a way to make Dot move the red node "out of the way", that is to the left or to the right, possibly curved, so that it does not go over the black edges. It is for an automatically generated graph that can contain more than two nodes, not necessarily all vertically

问题 I am trying to draw a 100 node multi-graph G in graphviz layout in python's networkx so I made two trials so far: Trial 1 nx.draw_graphviz function as follows nx.draw_graphviz(G) but I get the following error repeated for all nodes in the graph: Error: node 1, position [0.127506302389087, 0.3262608552621944], expected two doubles Then trying to figure a solution I used trial 2 A=nx.to_agraph(G) to get a pygraphviz graph but when I try to draw with nx.draw_graphviz(A) I get the following Error

问题 I have a string in a C++ Qt application (on Ubuntu) which contains valid GraphViz/dot graph syntax. I want to generate an image file/object from this text, similar to the images that various online tools (like this one: http://www.webgraphviz.com/) spit out. Maybe I'm using wrong search terms, but I can't seem to find relevant help with this. What I basically want is something like this: generate_dot_graph_image(std::string dot_text, std::string image_file_path) Additional details: I have a
