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，话不多说，直接上效果图：
发现，MsChart 的显示效果还是不错的。
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 (myChart_GetToolTipText); } void FrmMain_Load(object sender, EventArgs e) { float[][] data = new float[3][]; //第一条数据 data[0] = new float[10] { 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[1] = new float[12] { -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[2] = new float[10] { 7.8f, 9.2f, 6.5f, 8.3f, 9.0f, 5.9f, 6.3f, 7.2f, 8.8f, 9.8f }; for (int i = 0; i < data.Length; i++) { //横坐标时间 DateTime dt = DateTime.Now.Date; Series series = this.SetSeriesStyle(i); for (int j = 0; j < data[i].Length; j++) { series.Points.AddXY(dt, data[i][j]); dt = dt.AddDays(1); } 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[0]); } } /// /// 初始化Char控件样式 /// public void InitializeChart() { #region 设置图表的属性 //图表的背景色 myChart.BackColor = Color.FromArgb(211, 223, 240); //图表背景色的渐变方式 myChart.BackGradientStyle = GradientStyle.TopBottom; //图表的边框颜色、 myChart.BorderlineColor = Color.FromArgb(26, 59, 105); //图表的边框线条样式 myChart.BorderlineDashStyle = ChartDashStyle.Solid; //图表边框线条的宽度 myChart.BorderlineWidth = 2; //图表边框的皮肤 myChart.BorderSkin.SkinStyle = BorderSkinStyle.Emboss; #endregion #region 设置图表的Title Title title = new Title(); //标题内容 title.Text = "多曲线图演示"; //标题的字体 title.Font = new System.Drawing.Font("Microsoft Sans Serif", 12, FontStyle.Bold); //标题字体颜色 title.ForeColor = Color.FromArgb(26, 59, 105); //标题阴影颜色 title.ShadowColor = Color.FromArgb(32, 0, 0, 0); //标题阴影偏移量 title.ShadowOffset = 3; myChart.Titles.Add(title); #endregion #region 设置图表区属性 //图表区的名字 ChartArea chartArea = new ChartArea("Default"); //背景色 chartArea.BackColor = Color.FromArgb(64, 165, 191, 228); //背景渐变方式 chartArea.BackGradientStyle = GradientStyle.TopBottom; //渐变和阴影的辅助背景色 chartArea.BackSecondaryColor = Color.White; //边框颜色 chartArea.BorderColor = Color.FromArgb(64, 64, 64, 64); //阴影颜色 chartArea.ShadowColor = Color.Transparent; //设置X轴和Y轴线条的颜色和宽度 chartArea.AxisX.LineColor = Color.FromArgb(64, 64, 64, 64); chartArea.AxisX.LineWidth = 1; chartArea.AxisY.LineColor = Color.FromArgb(64, 64, 64, 64); chartArea.AxisY.LineWidth = 1; //设置X轴和Y轴的标题 chartArea.AxisX.Title = "横坐标标题"; chartArea.AxisY.Title = "纵坐标标题"; //设置图表区网格横纵线条的颜色和宽度 chartArea.AxisX.MajorGrid.LineColor = Color.FromArgb(64, 64, 64, 64); chartArea.AxisX.MajorGrid.LineWidth = 1; chartArea.AxisY.MajorGrid.LineColor = Color.FromArgb(64, 64, 64, 64); chartArea.AxisY.MajorGrid.LineWidth = 1; myChart.ChartAreas.Add(chartArea); #endregion #region 图例及图例的位置 Legend legend = new Legend(); legend.Alignment = StringAlignment.Center; legend.Docking = Docking.Bottom; this.myChart.Legends.Add(legend); #endregion } //设置Series样式 private Series SetSeriesStyle(int i) { Series series = new Series(string.Format("第{0}条数据", i + 1)); //Series的类型 series.ChartType = SeriesChartType.Line; //Series的边框颜色 series.BorderColor = Color.FromArgb(180, 26, 59, 105); //线条宽度 series.BorderWidth = 3; //线条阴影颜色 series.ShadowColor = Color.Black; //阴影宽度 series.ShadowOffset = 2; //是否显示数据说明 series.IsVisibleInLegend = true; //线条上数据点上是否有数据显示 series.IsValueShownAsLabel = false; //线条上的数据点标志类型 series.MarkerStyle = MarkerStyle.Circle; //线条数据点的大小 series.MarkerSize = 8; //线条颜色 switch (i) { case 0: series.Color = Color.FromArgb(220, 65, 140, 240); break; case 1: series.Color = Color.FromArgb(220, 224, 64, 10); break; case 2: series.Color = Color.FromArgb(220, 120, 150, 20); break; } return series; } } 另外附上微软Demo的下载地址：
Demo 分为WEB版本和WinForm版本，样式和图表内容很全，希望对大家有所帮助。
