Como imprimir um gráfico em graphviz com várias propriedades exibidas
Minha pergunta é baseada em:Como imprimir um gráfico com uma única propriedade exibida
Estou usando propriedades agrupadas:
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;
Eu tenho o seguinte chamado em um loop quedevemos crie as arestas:
edge prop;
prop.weight = 5;
prop.capacity = 4;
add_edge(ele.first,ele.second, prop, g);
Este segmento é o que imprime o gráfico ao formato de ponto.
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)));
O erro é:

É estranho para mim porque isso funciona:
write_graphviz(dot, g,
boost::make_label_writer(boost::get(&vert_info::name, g)));
e gera o seguinte:
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 ;
...
...
}
Meu objetivo é ter cada nó identificado e cada borda marcada com sua capacidade e peso.
