我在winform上画出来的带箭头直线为什么是这个样子？

Question

p.DashStyle = DashStyle.Solid;                       //定义实线
            p.EndCap = LineCap.ArrowAnchor;                     //定义线尾的样式为箭头
            while (k < N)
            {
                //gg.FillEllipse(myBrush, new Rectangle(point[j].X, point[j].Y, 10, 10));//画实心椭圆
                gg.DrawLine(p, point_edge[j].X, point_edge[j].Y, point_edge[j + 1].X, point_edge[j + 1].Y);
                j+=2;
                k++;
