How can I influence Graphviz/dot to make nicer control-flow graphs by removing snaking and better edge crossings?

由 和自甴很熟 提交于 2020-01-14 03:31:05
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

Explicit vertex position in python graph-tool

由 烂漫一生 提交于 2020-01-13 10:00:11
问题 I am using python graph-tool. To draw graphs, it uses graph_draw function. I want to send vertex positions explicitly to dot engine. It turns out that I can pass a property map named pos . I tried defining it as v_pos = g.new_vertex_property("vector<double>") where g is my graph. I am not sure if it is the right way to do it. There is one code snippet which you might find helpful. pos = gt.random_layout(g, shape=shape, dim=3) >>> pos[g.vertex(0)].a array([ 86.59969709, 1.31435598, 0.64651486]

Graphviz Dot vertical alignment of nodes

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

Rank attribute is confusing to me

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;

As I understand, it replaces DOTTreeGenerator in ANTLR4. 回答1: I am also interested in an answer to your question and didn't find a fully convincing one yet.

Generate image of GraphViz graph given dot text c++

由 吃可爱长大的小学妹 提交于 2020-01-03 03:45:07
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
