//populate dataset with some demo data.. DataSet dataSet = new DataSet(); DataTable dt = new DataTable(); dt.Columns.Add("Name", typeof(string)); dt.Columns.Add("Counter", typeof(int)); DataRow r1 = dt.NewRow(); r1[0] = "Demo"; r1[1] = 8; dt.Rows.Add(r1); DataRow r2 = dt.NewRow(); r2[0] = "Second"; r2[1] = 15; dt.Rows.Add(r2); dataSet.Tables.Add(dt); //prepare chart control... Chart chart = new Chart(); chart.DataSource = dataSet.Tables[0]; chart.Width = 600; chart.Height = 350; //create serie... Series serie1 = new Series(); serie1.Name = "Serie1"; serie1.Color = Color.FromArgb(112, 255, 200); serie1.BorderColor = Color.FromArgb(164, 164, 164); serie1.ChartType = SeriesChartType.Column; serie1.BorderDashStyle = ChartDashStyle.Solid; serie1.BorderWidth = 1; serie1.ShadowColor = Color.FromArgb(128, 128, 128); serie1.ShadowOffset = 1; serie1.IsValueShownAsLabel = true; serie1.XValueMember = "Name"; serie1.YValueMembers = "Counter"; serie1.Font = new Font("Tahoma", 8.0f); serie1.BackSecondaryColor = Color.FromArgb(0, 102, 153); serie1.LabelForeColor = Color.FromArgb(100, 100, 100); chart.Series.Add(serie1); //create chartareas... ChartArea ca = new ChartArea(); ca.Name = "ChartArea1"; ca.BackColor = Color.White; ca.BorderColor = Color.FromArgb(26, 59, 105); ca.BorderWidth = 0; ca.BorderDashStyle = ChartDashStyle.Solid; ca.AxisX = new Axis(); ca.AxisY = new Axis(); chart.ChartAreas.Add(ca); //databind... chart.DataBind(); //save result... chart.SaveImage(@"c:\myChart.png", ChartImageFormat.Png); 

将这个声明添加到你的类的顶部:

  using System.Windows.Forms.DataVisualization.Charting; 

绘制0至2pi之间的sin(x)。

您必须将“System.Windows.Forms.DataVisualization.dll”和“System.Drawing.dll”添加到您的项目。

祝你好运 :)
