graphviz

问题 I am very close to being able to generate a family tree that doesn't look terrible, but I'm running into the following problem. //file: tree.dot digraph { edge [dir=none]; node [ fillcolor="black",fixedsize=true,shape=box, style="rounded,filled",width=2.0 ]; splines=ortho; // GEN -01 { rank=same; rankdir=LR; "Grandfather" [regular=0]; m0002 [ label="",shape=diamond,regular=0,height=0.25, width=0.25,style="filled", ]; "Grandmother" [regular=0]; { rank=same; rankdir=LR; "Grandfather" -> m0002 -

问题 I am trying to do an example with read_graphviz but I can not help the linker to link the read_graphviz function call to the correct version read_graphviz. At http://www.boost.org/doc/libs/1_61_0/libs/graph/doc/read_graphviz.html there are three template versions of read_graphviz: namespace boost { template <typename MutableGraph> bool read_graphviz(std::istream& in, MutableGraph& graph, dynamic_properties& dp, const std::string& node_id = "node_id"); template <typename MutableGraph> bool

问题 I need to visualize a tree which I have gotten from an ANTLR parser and written to a .dot file by catching console output that the ANLR dot generator produces. MyDOTTreeGenerator generator = new MyDOTTreeGenerator(); PrintStream old = System.out; try { System.setOut(new PrintStream(new FileOutputStream(graphFile))); } catch (FileNotFoundException e) { e.printStackTrace(); } System.out.println(generator.toDOT(root)); System.out.flush(); System.setOut(old); Question is: 1. Is there a way to

问题 I am drawing control-flow graphs for Python programs and would like to influence which kind of edges should not be crossed over. Is there a way to do this? Consider this simple Python program: try: a += 1 except: a += 2 else: a = 3 And a dot program to represent the control flow for that generated via https://github.com/rocky/python-control-flow/ digraph G { mclimit=1.5; rankdir=TD; ordering=out; graph[fontsize=10 fontname="Verdana"]; color="#efefef"; node[shape=box style=filled fontsize=8

问题 NetworkX is mostly for graph analysis, PyGraphviz mostly for drawing, and they're designed to work together. However, there's at least one respect in which NetworkX's graph drawing (via MatPlotLib) is superior to PyGraphviz's graph drawing (via Graphviz), namely that NetworkX has a spring layout algorithm (accessible via the spring_layout function) specifically for directed graphs while PyGraphviz has several spring layout algorithms (accessible via the neato program, and others) that lay out

问题 I would like to change font attribute as the example below Is there any way to change the font of just few words inside a label instead of using the global attribute change fontname="times bold italic" ? I need to convert to png. 回答1: You may use HTML-like labels in graphviz and define labels with partially bold text: mynode [label=<<FONT FACE="boldfontname">bold text</FONT>>] Or use the <B> tag: mynode [label=< <B>bold text</B> regular text >] 回答2: If you are really desperate, you could also

问题 I got this dot graph and want the nodes A and D, B and E and C and F to be aligned. Here is the related dot code: digraph{ A B C D E F {rank = same; B; C} {rank = same; E; F} A -> B [label="2", weight=2] A -> C [label="0", style=dashed, weight=2] B -> C [label="0", style=dashed, weight=2] B -> D [label="2", style=dashed, weight=2] C -> D [label="0", weight=2] D -> E [label="1", style=dashed, weight=2] D -> F [label="0", weight=2] E -> F [label="0", weight=2] F -> A } As you can see I already

问题 Rank attribute on edge has five values "same", "min", "source", "max", "sink". Except "same", I have no idea when to use other values. min \begin{dotpic} rankdir=LR; size="7,5"; node[shape=circle]; C->A; {rank=min;A;B} B->D A->B; \end{dotpic} max \begin{dotpic} rankdir=LR; size="7,5"; node[shape=circle]; C->A; {rank=max;A;B} B->D A->B; \end{dotpic} source \begin{dotpic} rankdir=LR; size="7,5"; node[shape=circle]; C->A; {rank=source;A;B} B->D A->B; \end{dotpic} sink \begin{dotpic} rankdir=LR;
