所以，基本上我试图在两个椭圆的中心之间画一条线
我认为应该这样做：
Path myPath = new Path();
myPath.Stroke = System.Windows.Media.Brushes.Black;
myPath.StrokeThickness = 4;
myPath.HorizontalAlignment = HorizontalAlignment.Left;
myPath.VerticalAlignment = VerticalAlignment.Center;
EllipseGeometry myEllipseGeometry = new EllipseGeometry();
myEllipseGeometry.Center = new System.Windows.Point((xQuard * 10) + 100, yQuard * 10);
myEllipseGeometry.RadiusX = 2;
myEllipseGeometry.RadiusY = 2;
myPath.Data = myEllipseGeometry;
GraphPanel.Children.Add(myPath);
//if it's not the first point...
if (prevA != 0.0)
{
Path iLine = new Path();
iLine.Stroke = Brushes.Black;
iLine.StrokeThickness = 4;
iLine.HorizontalAlignment = HorizontalAlignment.Left;
myPath.VerticalAlignment = VerticalAlignment.Center;
LineGeometry iLineGeometry = new LineGeometry();
iLineGeometry.StartPoint = myEllipseGeometry.Center;
iLineGeometry.EndPoint = new System.Windows.Point(prevA, prevB);
iLine.Data = iLineGeometry;
GraphPanel.Children.Add(iLine);
}
//Set the previous point(s)
prevA = (xQuard * 10) + 100;
prevB = yQuard * 10;
现在如您所见，我已将 Line 的 StartPoint = 设置为第一个椭圆起点
但是....
为什么图中Line的起点不是左边点的中心？
