Hi,
I have the following code that print a graph taking in count values of dynamic_properties:
#include<iostream>
#include <boost/graph/adjacency_list.hpp>
#include <boost/graph/graphviz.hpp>
using namespace std;
using namespace boost;
struct VertexInfo
{
int id;
};
struct EdgeInfo
{
double weight;
bool enable;
};
typedef adjacency_list<listS, vecS, bidirectionalS, VertexInfo, EdgeInfo> Graph;
int main()
{
////////////////////////////////////////////////////////////////////////////////////////////
Graph graph;
Graph::vertex_descriptor a = add_vertex(graph);
Graph::vertex_descriptor b = add_vertex(graph);
Graph::vertex_descriptor c = add_vertex(graph);
Graph::vertex_descriptor d = add_vertex(graph);
Graph::edge_descriptor e1 = (add_edge(a, b, graph)).first;
Graph::edge_descriptor e2 = (add_edge(a, b, graph)).first;
Graph::edge_descriptor e3 = (add_edge(b, c, graph)).first;
Graph::edge_descriptor e4 = (add_edge(c, a, graph)).first;
Graph::edge_descriptor e5 = (add_edge(c, a, graph)).first;
Graph::edge_descriptor e6 = (add_edge(c, d, graph)).first;
graph[e1].weight = 5;
graph[e2].weight = 10;
graph[e3].weight = 6;
graph[e4].weight = 14;
graph[e5].weight = 2;
graph[e6].weight = 3;
graph[e1].enable = true;
graph[e2].enable = false;
graph[e3].enable = true;
graph[e4].enable = false;
graph[e5].enable = true;
graph[e6].enable = false;
ofstream ofs("graph.dot");
dynamic_properties dp;
dp.property("node_id", get(vertex_index, graph));
dp.property("label", get(&EdgeInfo::weight, graph));
dp.property("taillabel", get(&EdgeInfo::enable, graph));
write_graphviz_dp(ofs, graph, dp);
cout << "fin" << endl;
return 0;
}

there is a property called "enable" in the edges that I print in the tails of the arrows.
