Question

我需要自动绘制完整的图表。完整图表将取决于用户输入的节点数量。两个节点之间的权重是随机分配的。使用的方法效率低，因为要绘制九个节点的图形，用户必须在屏幕上点击九次。此外，为了在两个节点之间绘制边缘，用户必须最多在两个节点处右键单击以建立链接。我试图寻找一些在线的例子，但我似乎找不到任何东西。这就是我到目前为止所做的事情

CODE

    private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {

        Label v = new Label();
        v.Content = E;


        Ellipse cir = new Ellipse();
        cir.Width = 16.5;
        cir.Height = 16;

        circ.Stroke = Brushes.MediumAquamarine;
        circ.StrokeThickness = 2;
        CanvasMiddle.Children.Add(circ);

        Point a = e.GetPosition(circ);

        Canvas.SetLeft(circ, a.X-3);
        Canvas.SetTop(circle, a.Y+1);


        Vertex.Add(i, new Tuple<double, double>(a.X, a.Y));

        CanvasMiddle.Children.Add(value);

        Point coordinates = e.GetPosition(v);
        Canvas.SetLeft(v, coordinates.X-5);
        Canvas.SetTop(va, coordinates.Y-5);
            f++;

        i++;
    }

//生成两个节点之间的边缘

private void Window_MouseRightButtonDown(object sender, MouseButtonEventArgs e)

{

        for (int i = 1; i <= Node.Count; i++)
        {
            E1 = Node[i].Item1 - 13; a2 = Node[i].Item1 + 13;
            G1 = Node[i].Item2 - 13; b2 = Node[i].Item2 + 13;

            if ((P >= E1 && P <= G1) && (Q >= E1 && Q <= G1))
            {
                ID1[j] = i; 
                j++;



                if (j == 2)
                {
                    Line li = new Line();

                    li.X1 = Vertex[ID1[0]].Item1 + 5;
                    li.Y1 = Vertex[ID1[0]].Item2 + 5;
                    li.X2 =(line.X2-13)+ (Vertex[ID1[1]].Item1 + 5);
                    li.Y2 =(line.Y2) + (Vertex[ID1[1]].Item2 + 5);

                    li.Stroke = Brushes.MediumAquamarine;
                    li.StrokeThickness = 2;

                    Point co1 = e.GetPosition(li);
                    Canvas.SetLeft(li, co1.X+2.78);
                    Canvas.SetTop(li, co1.Y+1.85);


                    CanvasMiddle.Children.Add(li);

                    j = 0;

}
