In the .Net4.0 framework, Microsoft has integrated the Mschart control. It has been used in the web before. The original Mschart control under winform is simpler and more convenient. Today we use mschart to draw a multi-curve graph. , directly on the effect chart:
Found that MsChart's display is still good.
The code is as follows for your reference:
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[3][]; //First data 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 }; //Second data 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 }; //Third data 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++) { //Horizontal time 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("Time: {0}; Value: {1: F1} ", DateTime.FromOADate(dp.XValue),dp.YValues[0]); } } /// <summary> /// Initialize the Char control style /// </summary> public void InitializeChart() { #region Set the properties of the chart //Background color of the chart myChart.BackColor = Color.FromArgb(211, 223, 240); //Gradient way of chart background color myChart.BackGradientStyle = GradientStyle.TopBottom; //The border color of the chart, myChart.BorderlineColor = Color.FromArgb(26, 59, 105); //Border line style of the chart myChart.BorderlineDashStyle = ChartDashStyle.Solid; //The width of the chart border line myChart.BorderlineWidth = 2; //Chart border skin myChart.BorderSkin.SkinStyle = BorderSkinStyle.Emboss; #endregion #region Set the Title of the chart Title title = new Title(); //title content title.Text = "Multi-curve demonstration"; //Title font title.Font = new System.Drawing.Font("Microsoft Sans Serif", 12, FontStyle.Bold); //Title font color title.ForeColor = Color.FromArgb(26, 59, 105); //Header shadow color title.ShadowColor = Color.FromArgb(32, 0, 0, 0); //Header shadow offset title.ShadowOffset = 3; myChart.Titles.Add(title); #endregion #region Set chart area properties //The name of the chart area ChartArea chartArea = new ChartArea("Default"); //Background color chartArea.BackColor = Color.FromArgb(64, 165, 191, 228); //Background gradient chartArea.BackGradientStyle = GradientStyle.TopBottom; //Auxiliary background color for gradients and shadows chartArea.BackSecondaryColor = Color.White; //Border color chartArea.BorderColor = Color.FromArgb(64, 64, 64, 64); //Shadow color chartArea.ShadowColor = Color.Transparent; //Set the color and width of the X and Y axis bars 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; //Set the title of the X and Y axes chartArea.AxisX.Title = "Horizontal title"; chartArea.AxisY.Title = "Angular title"; //Set the color and width of the horizontal and vertical lines of the chart area grid 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 Legend and legend location Legend legend = new Legend(); legend.Alignment = StringAlignment.Center; legend.Docking = Docking.Bottom; this.myChart.Legends.Add(legend); #endregion } //Set the Series style private Series SetSeriesStyle(int i) { Series series = new Series(string.Format("{0} data", i + 1)); //Type of Series series.ChartType = SeriesChartType.Line; //Series border color series.BorderColor = Color.FromArgb(180, 26, 59, 105); //Line width series.BorderWidth = 3; //Line shadow color series.ShadowColor = Color.Black; //Shadow width series.ShadowOffset = 2; //Whether to display data description series.IsVisibleInLegend = true; //Is there any data display on the data points on the line? series.IsValueShownAsLabel = false; //Data point marker type on the line series.MarkerStyle = MarkerStyle.Circle; //Line data point size series.MarkerSize = 8; //Line color 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; } }
Also attach the download address of Microsoft Demo:http://archive.msdn.microsoft.com/mschart/Release/ProjectReleases.aspx?ReleaseId=4418
Demo is divided into WEB version and WinForm version. The style and chart content are very comprehensive, I hope to help everyone.
