我正在使用带有图形#库的WPF,我正在尝试将图形绘制为线性链,因此我定义了一些顶点,并将边连接为

new Edge<object>(vertices[i], vertices[i+1])

但问题是结果图未按预期绘制,如下所示:

1 - > 2 - > 3 - > 1-> 4

换句话说,顶点3穿过顶点1到达顶点4.

这是绘图方法的代码

private void CreateGraphToVisualize()
{
    var g = new BidirectionalGraph<object, IEdge<object>>();

    // add the vertices to the graph
    string[] vertices = new string[5];
    for (int i = 0; i < 5; i++)
    {
        vertices[i] = i.ToString();
        g.AddVertex(vertices[i]);
    }

    // add edges to the graph
    g.AddEdge(new Edge<object>(vertices[0], vertices[1]));
    g.AddEdge(new Edge<object>(vertices[1], vertices[2]));
    g.AddEdge(new Edge<object>(vertices[2], vertices[3]));
    g.AddEdge(new Edge<object>(vertices[3], vertices[4]));

    GraphToVisualize = g;
}

这是与图形相关的xaml代码的一部分#

<DockPanel Grid.Row="2" …

我正在使用GraphSharp框架,它只有很少的文档(http://graphsharp.codeplex.com/),我正在尝试更改某些边缘的颜色.

实际上是这样的(使这个边缘变红).

g.AddEdge(new Edge<object>("A","B"), Color.Red);

有人为此有任何代码片段吗？

我目前正在开发一个Visual Studio插件(VSPackage),它最终应该能够可视化调用关系.为了表示它们,我想使用管理图形的Graph#库(避免重叠边缘等).不幸的是,我在运行时在我的XAML中收到以下错误消息:

XamlParseException:未实现方法或操作.

<graph:CallRelationGraphLayout Graph="{Binding RelationGraph}"/>标签上会弹出错误.

我还创建了自己的顶点,边和图布局类.我的图最终应该表示方法(顶点)之间的调用关系(边).

MethodVertex.cs

public class MethodVertex
{
    public string ID { get; private set; }
    public bool IsMale { get; private set; }

    public MethodVertex(string id, bool isMale)
    {
        ID = id;
        IsMale = isMale;
    }

    public …

这是我的窗口代码:

public partial class MainWindow
{
    private MainWindowViewModel _mainWindowViewModel;

    public MainWindow()
    {
        InitializeComponent();
        _mainWindowViewModel = new MainWindowViewModel();
        DataContext = _mainWindowViewModel;
    }
}

和视图模型代码:

class MainWindowViewModel : ViewModelBase
{
    private BidirectionalGraph<string, IEdge<string>> _graph;

    public BidirectionalGraph<string, IEdge<string>> Graph
    {
        get { return _graph; }
        set
        {
            _graph = value;
            NotifyPropertyChanged("Graph");
        }
    }

    public MainWindowViewModel()
    {
        Graph = new BidirectionalGraph<string, IEdge<string>>();

        // test data
        const string vertex1 = "123";
        const string vertex2 = "456";
        const string vertex3 = "ddd";

        Graph.AddVertex(vertex1);
        Graph.AddVertex(vertex2);
        Graph.AddVertex(vertex3);
        Graph.AddEdge(new …

我尝试使用 CodePlex 的 GraphSharp 创建一棵树。

我查看了示例应用程序并尝试“重新设计”该示例。

问题是，如果我尝试以编程方式设置 LayoutAlgorithmType = "Tree" ，我会得到一个 TargetInvocationException ... 这很神秘，因为在示例中它有效。

我的问题是：如何创建具有树布局和从左到右方向的图形。

提前致谢 ：）

我的代码：

public partial class MainWindow : Window
{
    private IBidirectionalGraph<object, IEdge<object>> _graphToVisualize;

    public IBidirectionalGraph<object, IEdge<object>> GraphToVisualize
    {
        get { return _graphToVisualize; }
    }

    public MainWindow()
    {
        CreateGraphToVisualize();

        InitializeComponent();
    }

    private void CreateGraphToVisualize()
    {
        var g = new BidirectionalGraph<object, IEdge<object>>();



        string[] vs = new string[5];
        for (int i = 0; i < 5; i++)
        {
            vs[i] = i.ToString();
            g.AddVertex(vs[i]);
        }

        //add some edges
        g.AddEdge(new …
