google了一把tchart控件,看到许多都没有讲到数据绑定的。没事就做个简单的demo。不在赘述,如下:
tChart1.Header.Text = "报告测试"; tChart1.Aspect.View3D = false; tChart1.Axes.Bottom.Labels.DateTimeFormat = "yyyy-MM-dd";////把X坐标轴刻度设置成时间类型,Axes是坐标轴的意思,Bottom是X轴,也可以选择其他轴 tChart1.Axes.Bottom.Labels.MultiLine = true; //tChart1.Axes.Bottom.SetMinMax(DateTime.Now.AddYears(8), DateTime.Now);
line1.Title = "曲线名字"; line1.Color = Color.Red; line2.Color = Color.SeaGreen; line3.Color = Color.Yellow;
tChart1.Legend.CheckBoxes = true;
string constr = "Data Source=.;Initial Catalog=OnlineTestData_Lite;Integrated Security=True"; SqlConnection con = new SqlConnection(constr); SqlDataAdapter da = new SqlDataAdapter("select ID,TestDateTime,ueff_0,ueff_1,ueff_2 from Process_Data where testdatetime > '2010-01-01 22:22:22'", con); DataTable dt = new DataTable(); da.Fill(dt); line1.DataSource = dt; line1.XValues.DataMember = "TestDateTime"; line1.YValues.DataMember = "ueff_1"; line1.LabelMember = "TestDateTime"; line2.DataSource = dt; line2.XValues.DataMember = "TestDateTime"; line2.YValues.DataMember = "ueff_2"; line2.LabelMember = "TestDateTime"; line3.DataSource = dt; line3.XValues.DataMember = "TestDateTime"; line3.XValues.DateTime = true; line3.YValues.DataMember = "ueff_0"; line3.LabelMember = "TestDateTime";
//调用 cursorTool1_Change(tChart1, new Steema.TeeChart.Tools.CursorChangeEventArgs());
效果图如下所示:
