How to print a graph in graphviz with multiple pro

My question is based off of: How to print a graph with a single property displayed

I am using bundled properties:

 typedef struct vert{
   std::string name;
 };

 typedef struct edge{
   int capacity;
   int weight;
 }; 

typedef adjacency_list<listS, vecS, undirectedS, vert, edge> Graph;
Graph g;
vector<int,int> ele;

I have the following called in a loop that should create the edges:

  edge prop;
  prop.weight = 5;
  prop.capacity = 4;
  add_edge(ele.first,ele.second, prop, g);

This segment is what prints the graph to dot format.

ofstream dot("graph.dot");
write_graphviz(dot, g, 
  boost::make_label_writer(boost::get(&vert::name, g)),
  boost::make_label_writer(boost::get(&edge::weight, g)),
  boost::make_label_writer(boost::get(&edge::capacity, g)));

The error is:

It is strange to me because this works:

write_graphviz(dot, g,
  boost::make_label_writer(boost::get(&vert_info::name, g)));

and outputs the following:

graph G {
0[label="0"];
1[label="1"];
2[label="2"];
3[label="3"];
4[label="4"];
5[label="5"];
6[label="6"];
7[label="7"];
8[label="8"];
9[label=""];  // this is another problem that I will have to fix but beside the point
0--9 ;
0--5 ;
0--2 ;
0--1 ;
...
...
}

My goal is to have each node labeled, and each edge labelled with its capacity and weight.

You can find here the list of all the overloads for write_graphviz. The reason for your first error is that the overload you tried to use expects a graph property writer in its fifth argument.

The helper function make_label_writer simply creates a property writer that assigns a single property from either a vertex or an edge of your graph to a graphviz vertex or edge attribute named label.

In order to achieve what you want you need to create a custom property writer in which you assign each of your edge properties to the graphviz attributes you need. I would personally use weight->label and capacity->taillabel or headlabel.

template <class WeightMap,class CapacityMap>
class edge_writer {
public:
  edge_writer(WeightMap w, CapacityMap c) : wm(w),cm(c) {}
  template <class Edge>
  void operator()(ostream &out, const Edge& e) const {
    out << "[label=\"" << wm[e] << "\", taillabel=\"" << cm[e] << "\"]";
  }
private:
  WeightMap wm;
  CapacityMap cm;
};

template <class WeightMap, class CapacityMap>
inline edge_writer<WeightMap,CapacityMap> 
make_edge_writer(WeightMap w,CapacityMap c) {
  return edge_writer<WeightMap,CapacityMap>(w,c);
}

And finally your write_graphviz invocation would simply be:

ofstream dot("graph.dot");
write_graphviz(dot, g, 
  boost::make_label_writer(boost::get(&vert::name, g)),
  make_edge_writer(boost::get(&edge::weight,g),boost::get(&edge::capacity,g)));
