如何在显示属性之一的 graphviz 中打印增强图?
我在使用属性映射时看到了这样的例子,但在使用结构来处理顶点和边时却没有看到(我认为这被称为包").
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').
我在邻接列表图中定义了顶点和边.
I have vertices and edges defined as such, in an adjacency list graph.
struct Vertex
{
string name;
int some_int;
};
struct Edge
{
double weight;
};
图的构造如下:
typedef boost::adjacency_list<boost::listS, boost::vecS, boost::directedS, Vertex, Edge> boost_graph;
我想以 Graphviz
格式打印这些对象的图形,以便我可以将其作为图像查看.但是,我不仅想要节点和边.我还希望顶点上的属性 name
和边缘上的 weight
出现在图像中.我该怎么做?
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?
推荐答案
我第一次提供了错误信息.这是正确答案.
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]));
