利用MsChart控件绘制多曲线图表

在.Net4.0框架中，微软已经将Mschart控件集成了进来，以前一直在web下面用过，原来winform下的Mschart控件更加简单更加方便，今天我们用mschart绘制一个多曲线图，发现MsChart 的显示效果还是不错的，话不多说，直接上效果图：

代码如下，供大家参考：

public partial class FrmMain : Form

    {

        public FrmMain()

        {

            InitializeComponent();

            InitializeChart();

            this.Load += new EventHandler(FrmMain_Load);

            this.myChart.GetToolTipText += new EventHandler<ToolTipEventArgs>(myChart_GetToolTipText);

        }

        void FrmMain_Load(object sender, EventArgs e)

        {

            float[][] data = new float[][];

            //第一条数据

            data[] = new float[] { 1.3f, 2.5f, 2.1f, 3.3f, 2.8f, 3.9f, 4.3f, 3.6f, 4.2f, 3.6f };

            //第二条数据

            data[] = new float[] { -2f, -1.3f, 0.1f, 0.5f, -1.5f, 0.7f, 1f, 1.4f, 1.9f, 2f, 2.6f, 3.1f };

            //第三条数据

            data[] = new float[] { 7.8f, 9.2f, 6.5f, 8.3f, 9.0f, 5.9f, 6.3f, 7.2f, 8.8f, 9.8f };

            for (int i = ; i < data.Length; i++)

            {

                //横坐标时间

                DateTime dt = DateTime.Now.Date;

                Series series = this.SetSeriesStyle(i);

                for (int j = ; j < data[i].Length; j++)

                {

                    series.Points.AddXY(dt, data[i][j]);

                    dt = dt.AddDays();

                }

                this.myChart.Series.Add(series);

            }

        }

        private void myChart_GetToolTipText(object sender, ToolTipEventArgs e)

        {

            if (e.HitTestResult.ChartElementType == ChartElementType.DataPoint)

            {

                int i = e.HitTestResult.PointIndex;

                DataPoint dp = e.HitTestResult.Series.Points[i];

                e.Text = string.Format("时间:{0};数值:{1:F1} ", DateTime.FromOADate(dp.XValue),dp.YValues[]);

            }

        }
