如何在显示属性之一的 graphviz 中打印增强图?

How to print a boost graph in graphviz with one of the properties displayed?(如何在显示属性之一的 graphviz 中打印增强图?)

问题描述

我在使用属性映射时看到了这样的例子，但在使用结构来处理顶点和边时却没有看到(我认为这被称为包").

I see examples of this when using property maps, but not when using structs to handle the vertices and edges (I think this is called 'bundles').

我在邻接列表图中定义了顶点和边.

I have vertices and edges defined as such, in an adjacency list graph.

struct Vertex
{
    string name;
    int some_int;
};

struct Edge
{
    double weight;
};

图的构造如下:

typedef boost::adjacency_list<boost::listS, boost::vecS, boost::directedS, Vertex, Edge> boost_graph;

我想以 Graphviz 格式打印这些对象的图形，以便我可以将其作为图像查看.但是，我不仅想要节点和边.我还希望顶点上的属性 name 和边缘上的 weight 出现在图像中.我该怎么做?

I want to print my graph of these objects in Graphviz format, so I can view it as an image. However, I don't only want the nodes and edges. I also want the attribute name on vertices and weight on edges to appear in the image. How can I do this?

推荐答案

我第一次提供了错误信息.这是正确答案.

I gave bad info the first time. Here is the correct answer.

#include <boost/graph/graphviz.hpp>

using namespace boost;

// Graph type
typedef adjacency_list<vecS, vecS, directedS, VertexProperties, EdgeProperty> Graph;
Graph g;
std::vector<std::string> NameVec; // for dot file names


// write the dot file
std::ofstream dotfile (strDotFile.c_str ());
write_graphviz (dotfile, g, make_label_writer(&NameVec[0]));
