c# 使用 Tchart控件之数据绑定

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：
