C# chart1.Series[0].ToolTip 如何获取Datatable 的值

[tg_hgh163]

  chart1.Series.Clear();
                chart1.ChartAreas.Clear();
                Series Series1 = new Series("Dt");
                Series1.Points.DataBind(Dt.AsEnumerable(), "库位", "托盘数", "");               
                Series1.XValueType = ChartValueType.String; //设置X轴类型
                Series1.ChartType = SeriesChartType.Bar;  //设置Y轴为柱状
                chart1.Series.Add(Series1);
                chart1.Series[0].ChartType = SeriesChartType.Column;
                chart1.Legends[0].Enabled = false;
                chart1.Series[0].LegendText = "";
                chart1.Series[0].Label = "#VALY";
                chart1.Series[0].Font = new Font("宋体", 10, FontStyle.Bold);
                chart1.Series[0].LabelForeColor = Color.Blue;

                chart1.Series[0].ToolTip = "库位：#VALX\r\n托盘数：#VALY\r\n库位限量:%#Eval(\"库位限量\")%";// "#VALX";

获取X轴值用 #VALX，Y轴用 #VALY， 还想获取一个 库位限量的值

自己回答一下吧： 要循环设置 chart1.Series[0].Points[i].ToolTip = “” ; 可以通过 i 定位到 Dt中的数据 直接设置 chart1.Series[0].ToolTip =""; 只能设置Xy轴的值
