C#怎么把散点图画在chart控件上？

我这样写的。貌似不对。新手。x,y中分别存着n个double型的数据。我想把(x[i],y[i])显示在图上。（i=0到n-1）
this.chart1.Series[0].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Point;

        this.chart1.ChartAreas[0].AxisY.Maximum = 5.0D;
        this.chart1.ChartAreas[0].AxisY.Minimum = 0.0D;
        this.chart1.ChartAreas[0].CursorY.Interval = 0.01D;

        this.chart1.ChartAreas[0].AxisX.Maximum = 60.0D;
        this.chart1.ChartAreas[0].AxisX.Minimum = 0.0D;

        this.chart1.ChartAreas[0].CursorX.Interval = 0.01D;
        this.chart1.ChartAreas[0].CursorX.IntervalOffset = 0.01D;
        for(int i=0;i<c1.y.Length;i++)
        {
            double x2;
            double y2;
            x2 = (double)x[i];
            y2 = (double)y[i];
        }
        this.chart1.Series[0].Points.AddXY(x2, y2);

解决方案

建议试下telerik，官方demo也很详细的。记得有撒点图
