With the dynamic property code I posted previously you should be able to just change that write_graphviz_dp call to write_graphviz(ofs, G0). Here's some code as per my original post. With boost trunk it's currently failing with... include/boost/pending/property.hpp:126:5: error: no type named ‘type’ in ‘struct boost::lookup_one_property_internal<boost::no_property, boost::graph_graph_attribute_t>’ Thanks, Chris #include <boost/config.hpp> #include <iostream> #include <fstream> #include <boost/graph/subgraph.hpp> #include <boost/graph/adjacency_list.hpp> #include <boost/graph/graph_utility.hpp> #include <boost/graph/graphviz.hpp> int main(int,char*[]) { using namespace boost; typedef adjacency_list_traits<vecS, vecS, directedS> Traits; typedef property<vertex_color_t, int> vertex_p; typedef property<edge_index_t, int> edge_p; typedef property<graph_name_t, std::string> graph_p; typedef subgraph< adjacency_list<vecS, vecS, directedS, vertex_p, edge_p, graph_p > > Graph; const int N = 6; Graph G0(N); enum { A, B, C, D, E, F}; // for conveniently refering to vertices in G0 Graph& G1 = G0.create_subgraph(); Graph& G2 = G0.create_subgraph(); enum { A1, B1, C1 }; // for conveniently refering to vertices in G1 enum { A2, B2 }; // for conveniently refering to vertices in G2 add_vertex(C, G1); // global vertex C becomes local A1 for G1 add_vertex(E, G1); // global vertex E becomes local B1 for G1 add_vertex(F, G1); // global vertex F becomes local C1 for G1 add_vertex(A, G2); // global vertex A becomes local A1 for G2 add_vertex(B, G2); // global vertex B becomes local B1 for G2 add_edge(A, B, G0); add_edge(B, C, G0); add_edge(B, D, G0); add_edge(E, B, G0); add_edge(E, F, G0); add_edge(F, D, G0); add_edge(A1, C1, G1); // (A1,C1) is subgraph G1 local indices for (C,F). const char* names[] = { "A", "B", "C", "D", "E", "F" }; const char* enames[] = { "0", "1", "2", "3", "4", "5" }; const char* gnames[] = { "G0", "G1", "G2" }; std::ofstream ofs("out.dot"); #if 0 // works write_graphviz(ofs, G0.m_graph, make_label_writer(names)); #else write_graphviz(ofs, G0); //write_graphviz(ofs, G0, make_label_writer(names), make_label_writer(enames), make_label_writer(gnames)); #endif return 0; } On 2 August 2012 11:58, Jeremiah Willcock <jewillco@osl.iu.edu> wrote:

Thanks Jeremiah,
I've now got something that compiles and runs, but still doesn't include 'subgraph' clauses in the dot output and corresponding rectangles when rendered. Interestingly if I now change back to write_graphviz(ofs, G0) I do get some subgraph clauses, but the names are messed up presumably since they're now being set up using dynamic properties. Also the subgraphs still don't render in this case.
It looks like you do need to use write_graphviz (without _dp) to get subgraphs in the output. Could you please try your original code with the Boost trunk and see what happens? That will allow your line numbers to match up with mine. Also, a full code example using write_graphviz would be helpful. Thank you.
