How to print a boost graph in graphviz with one of the properties displayed?


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').

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

struct Vertex
{
    string name;
    int some_int;
};

struct Edge
{
    double weight;
};

The graph is constructed as follows:

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

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?


Solution

  • 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]));
