數據點插入錯誤。此數據系列只能設置1個Y值

Question

我正在嘗試顯示與我的數據庫連接的圖表。但它會產生一個錯誤。錯誤是「數據點插入錯誤，只能爲該數據系列設置1個Y值」。請幫幫我。 的代碼如下：

public partial class chart3 : System.Web.UI.Page 
{ 
    SqlConnection con; 
    SqlCommand cmd; 
    SqlDataAdapter da; 
    DataTable dt; 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     con = new SqlConnection(@"connectionString"); 
     cmd = new SqlCommand("Select * from GraphChart",con); 
     da = new SqlDataAdapter(cmd); 
     dt = new DataTable(); 
     da.Fill(dt); 
     Chart1.DataSource = dt; 
     Chart1.DataBind(); 
    } 
} 

來源：

<div> 
<asp:Chart ID="Chart1" runat="server" CssClass="auto-style1" Width="423px"> 
      <Series> 
       <asp:Series Name="Series1" XValueMember="Name"></asp:Series> 
       <asp:Series Name="Series2" YValueMembers="Age"></asp:Series> 

      </Series> 
      <ChartAreas> 
       <asp:ChartArea Name="ChartArea1"></asp:ChartArea> 
      </ChartAreas> 
      <Legends> 
       <asp:Legend Title="Employee Data"></asp:Legend> 
      </Legends> 
     </asp:Chart> 
</div> 

Answer 1

下面的代碼給定的工作。謝謝你們。

public partial class chart3 : 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 * from GraphChart",con); 
     da = new SqlDataAdapter(cmd); 
     ds = new DataSet(); 
     da.Fill(ds); 
     DataView source = new DataView(ds.Tables[0]); 
     Chart1.DataSource = source; 
     Chart1.Series[0].XValueMember = "Name"; 
     Chart1.Series[0].YValueMembers = "Age"; 
     Chart1.DataBind(); 
    } 
}

你可能會設置標籤，而不是真實數據。
