如何在不使用JS的情况下一次在ASP.NET中显示多重系列工具提示

Question

我如何使用C＃

使用比较选项

for (int k = 1; k < dt.Columns.Count; k++)
{
    object[] objects = new object[numOfObjects];
    for (int i = 0; i < dt.Rows.Count; i++)
    {
        if ((dt.Rows[i][k]).ToString() != string.Empty)
        {
            float value = Convert.ToSingle(dt.Rows[i][k]);
            objects[i] = (object)value;
        }
    }
    series.Add(new Serie { data = objects, name = input[k-1] });
    hcColumnChart.DataSource = series;
    hcColumnChart.DataBind();
}

我认为您正在同一图表上的多个系列？

for (int k = 1; k < dt.Columns.Count; k++)
 {
  Series series = new Series();
  for (int i = 0; i < dt.Rows.Count; i++)
   {
     if ((dt.Rows[i][k]).ToString() != string.Empty)
      {
        float value = Convert.ToSingle(dt.Rows[i][k]);
        series.Points.AddXY("enter_your_seriesname", value);
      }
   }
  hcColumnChart.Series.Add(series);
  hcColumnChart.DataBind();
}
