chart绘制实时曲线

//设置曲线样式
Series series =new Series("spline");
//画样条曲线（Spline）
series.ChartType = SeriesChartType.Spline;
//线宽2个像素
series.BorderWidth = 2;
//线的颜色：红色
series.Color = System.Drawing.Color.Red;
//图示上的文字
series.LegendText = "演示曲线";
//准备数据
Random random = new Random();
series.Points.AddXY(DateTime.Now.Second,random.Next(0,100));
chart2.Series.Add(series);
ChartArea chartArea = chart2.ChartAreas[0];
chartArea.AxisX.Minimum = 0;
//chartArea.AxisX.Maximum = 10;
chartArea.AxisY.Minimum = 0d;
//chartArea.AxisY.Maximum = 100d;
不知道哪的问题不出图

丫~~~~~~~真心没有这么玩过，chart真的可以同时显示三种形态么,求可运行的demo代码学习啊~~~~~~
