图表形式不正确

Question

我正在使用C＃语言处理Asp.Net图表。我向用户提供选项，他从数据库中选择字段并形成图表，还可以选择使用名称保存这些设置当用户想要查看他的保存设置时，他只需点击并绘制图形，然后制作一个智能列表。但是当用户点击他的保存设置图表的名称不正确并且没有正确显示轴时，我的代码如下：

protected void btnShowSmartList_Click(object sender, EventArgs e)
{
        string _SmartList ;
        ds = GetDataSet("SELECT [Sql_Query] FROM [DWH_SmartList] WHERE sys_SmartList_No=" + ddSmartQueryList.SelectedValue)   ;
        _SmartList = Convert.ToString(ds.Tables[0].Rows[0]["Sql_Query"]);

        ds.Tables[0].Dispose();
        ds = new DataSet();
        ds = GetDataSet(_SmartList);
        Chart1.DataSource = ds;
        Chart1.Legends.Add("Inspection_Date").Title = "Inspection_Date";
        Chart1.ChartAreas["ChartArea1"].AxisX.Title = Dd_List.SelectedValue;
        Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisX.MajorTickMark.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisY.MajorTickMark.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisX.MinorGrid.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisX.MinorTickMark.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisY.MinorGrid.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisY.MinorTickMark.Enabled = false;
        Chart1.ChartAreas["ChartArea1"].AxisY.Title = Dd_ListY.SelectedValue;
        Chart1.Series["Series1"].XValueMember = Dd_List.SelectedValue;
        Chart1.Series["Series1"].YValueMembers = Dd_ListY.SelectedValue;
        Chart1.Series["Series1"].LegendText = Dd_ListY.SelectedValue;

        this.GridFormatting();
        Chart1.DataBind();
        //Chart1.BackColor = System.Drawing.Color.White;
        // this.Chart1.ChartAreas["ChartArea1"].AxisY.IsStartedFromZero = false;

        GridView1.SelectedIndex = 0;
        GridView1.DataSource = ds;
        GridView1.DataBind();
    }

网格运行良好，但图形不是

我自己先解决了这个问题，然后用这段代码保存了所有Axis数据库中的值

{

    string connectionString = ConfigurationManager.ConnectionStrings["KTConnectionString"].ToString();
    cmd.Connection = con;
    KTDataContext dataContext = new KTDataContext(connectionString);
    DWH_SmartList tbip = new DWH_SmartList();
    tbip.Sql_Query = txtQuery.Text;
    tbip.Y_Axis = Dd_ListY.SelectedValue;
    tbip.Y1_Axis = Dd_ListYSec.SelectedValue;
    tbip.Y2_Axis = Dd_List3.SelectedValue;
    tbip.Y3_Axis = Dd_List4.SelectedValue;
    tbip.Y4_Axis = Dd_List5.SelectedValue;
    tbip.SmartList_Description = txt_SmartList.Text;
    tbip.User_Code = Convert.ToInt32(  Session["UserCode"]); 
    dataContext.DWH_SmartLists.InsertOnSubmit(tbip);
    dataContext.SubmitChanges();
}

然后我通过这段代码检索它： {

    string _SmartList,_yaxis,_y1axis,_y2axis,_y3axis,_y4axis,_y5axis;
    ds = GetDataSet("SELECT [Sql_Query],[Y_Axis],[Y1_Axis],[Y2_Axis],[Y3_Axis],[Y4_Axis],[Y5_Axis] FROM [DWH_SmartList] WHERE sys_SmartList_No=" + ddSmartQueryList.SelectedValue)   ;
    _SmartList = Convert.ToString(ds.Tables[0].Rows[0]["Sql_Query"]);

    _yaxis = Convert.ToString(ds.Tables[0].Rows[0]["Y_Axis"]);
    _y1axis= Convert.ToString(ds.Tables[0].Rows[0]["Y1_Axis"]);
    _y2axis = Convert.ToString(ds.Tables[0].Rows[0]["Y2_Axis"]);
    _y3axis = Convert.ToString(ds.Tables[0].Rows[0]["Y4_Axis"]);
    _y4axis = Convert.ToString(ds.Tables[0].Rows[0]["Y4_Axis"]);
    _y5axis = Convert.ToString(ds.Tables[0].Rows[0]["Y5_Axis"]);
    Dd_ListY.SelectedValue = _yaxis ;
    Dd_ListYSec.SelectedValue = _y1axis;
    Dd_List3.SelectedValue = _y2axis;
    Dd_List4.SelectedValue = _y3axis;
    Dd_List5.SelectedValue = _y4axis;
    ds.Tables[0].Dispose();
    ds = new DataSet();
    ds = GetDataSet(_SmartList);
    Chart1.DataSource = ds;
    Chart1.Legends.Add("Inspection_Date").Title = "Inspection_Date";
    Chart1.ChartAreas["ChartArea1"].AxisX.Title = Dd_List.SelectedValue;
    Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisX.MajorTickMark.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisY.MajorTickMark.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisX.MinorGrid.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisX.MinorTickMark.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisY.MinorGrid.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisY.MinorTickMark.Enabled = false;
    Chart1.ChartAreas["ChartArea1"].AxisY.Title = Dd_ListY.SelectedValue;
    Chart1.Series["Series1"].XValueMember = Dd_List.SelectedValue;
    Chart1.Series["Series1"].YValueMembers = Dd_ListY.SelectedValue;
    Chart1.Series["Series1"].LegendText = Dd_ListY.SelectedValue;



    this.GridFormatting();
    Chart1.DataBind();
    //Chart1.BackColor = System.Drawing.Color.White;
    // this.Chart1.ChartAreas["ChartArea1"].AxisY.IsStartedFromZero = false;




    GridView1.SelectedIndex = 0;
    GridView1.DataSource = ds;
    GridView1.DataBind();

}
