C# 数据点插入错误。此数据系列只能设置1个Y值。？8

我想生成一个条形图并动态显示其详细信息。我试图用四个值显示条形图。但它不起作用。我的代码如下。请帮帮我

   public partial class chartDummy : System.Web.UI.Page
{
    SqlConnection con;
    SqlCommand cmd;
    SqlDataAdapter da;
    DataSet ds;

    protected void Page_Load(object sender, EventArgs e)
    {
        con = new SqlConnection(@"ConnectionString");
        cmd = new SqlCommand("Select Mains_Run_Hrs, DG_Run_Auto_Mode, Battery_Run_Hrs, Solar_Run_hrs from tbl_runtime_report", con);
        da = new SqlDataAdapter(cmd);
        ds = new DataSet();
        da.Fill(ds);
        DataView source = new DataView(ds.Tables[0]);
            Chart1.DataSource = ds;
            Chart1.Series[0].XValueMember = "Mains_Run_Hrs";
            Chart1.Series[0].XValueMember = "DG_Run_Auto_Mode";
            Chart1.Series[0].XValueMember = "Battery_Run_Hrs";
            Chart1.Series[0].XValueMember = "Solar_Run_hrs";
            Chart1.DataBind();

    }   
}

      <asp:Chart ID="Chart1" runat="server" CssClass="auto-style1" Width="558px">
          <Series>

下面给出的代码工作正常。它根据数据库数据显示流量字符。多谢各位

public partial class chartDummy : System.Web.UI.Page
{
    SqlConnection con;
    SqlCommand cmd;
    SqlDataAdapter da;
    DataSet ds;

    protected void Page_Load(object sender, EventArgs e)
    {
        con = new SqlConnection(@"ConnectionString");
        cmd = new SqlCommand("Select Mains_Run_Hrs, DG_Run_Auto_Mode, Battery_Run_Hrs, Solar_Run_hrs from tbl_runtime_report", con);
        da = new SqlDataAdapter(cmd);
        ds = new DataSet();
        da.Fill(ds);
        DataView source = new DataView(ds.Tables[0]);
            Chart1.DataSource = ds;
            Chart1.Series[0].YValueMembers = "Mains_Run_Hrs";
            Chart1.Series[0].XValueMember = "DG_Run_Auto_Mode";
            Chart1.Series[0].XValueMember = "Battery_Run_Hrs";
            Chart1.Series[0].XValueMember = "Solar_Run_hrs";
            Chart1.DataBind();

    }   
}

state.GetDummyChart返回的是什么？您不应该将结果分配给DataTable而不是DataSet吗？@DavidG:我已经更新了代码。但是它产生了另一个错误。现在你完全改变了这个问题。另外，你填充图表的代码基本上都是胡说八道。@DavidG：实际上我只是asp.net的初学者。你能帮我吗。你有什么解决办法吗？我建议你去了解一下图表控件：
