用c#和dundas创建多个条形图

大家好，我在代码中添加条形图时遇到了麻烦。我要做的是从饼状图中为每一部分做一个柱状图。不幸的是，我很难做到这一点。我尝试做的主要目标是基于GroupName创建一个单独的详细条形图。这是我的c#代码:

    void StartReport10()
    {
        Chart c = Chart11;
        string str = ConfigurationManager.ConnectionStrings["SLRC_debug"].ConnectionString;
        SqlConnection con = new SqlConnection(str);
        SqlDataAdapter da = new SqlDataAdapter("sp_SLRC_GetReport_MajorAndMinorCauseCategories", con);
        da.SelectCommand.CommandType = CommandType.StoredProcedure;
        da.SelectCommand.CommandTimeout = 60; //(1 minute)
        da.SelectCommand.Parameters.Add(new SqlParameter("@rtype", SqlDbType.Int)).Value = Timeline10.RangeTypeIndex;
        da.SelectCommand.Parameters.Add(new SqlParameter("@y1", SqlDbType.Int)).Value = Convert.ToInt32(Timeline10.FYFrom);
        da.SelectCommand.Parameters.Add(new SqlParameter("@r1", SqlDbType.Int)).Value = Convert.ToInt32(Timeline10.RangeFrom);
        da.SelectCommand.Parameters.Add(new SqlParameter("@y2", SqlDbType.Int)).Value = Convert.ToInt32(Timeline10.FYTo);
        da.SelectCommand.Parameters.Add(new SqlParameter("@r2", SqlDbType.Int)).Value = Convert.ToInt32(Timeline10.RangeTo);
        int top = Int32.Parse(tbTop1.Text);
        da.SelectCommand.Parameters.Add(new SqlParameter("@top", SqlDbType.Int)).Value = top;
        da.SelectCommand.Parameters.Add(new SqlParameter("@MROProjFilter", SqlDbType.VarChar)).Value = MROProjReport3.GetSelectedMROProjFilter;
        da.SelectCommand.Parameters.Add(new SqlParameter("@TradeIntercoFilter", SqlDbType.VarChar)).Value = TradeInterco3.GetSelectedIntercoTradeFilter;
        if (CustomerFilter2.IsEnabled && CustomerFilter2.IsValid)
        {
            string a = CustomerFilter2.GetStrSelection;
            da.SelectCommand.Parameters.Add(new SqlParameter("@str", SqlDbType.VarChar)).Value = a;
        }
        DataSet ds = new DataSet();
        da.Fill(ds);
        ds.Tables["Table"].TableName = "Table_for_Major";
        ds.Tables["Table1"].TableName = "Table_for_Detailed";
        c.DataSource = ds.Tables["Table_for_Major"];
        c.Series.Clear();
        c.Series.Add("Default");
        c.Series[0].ValueMemberX = "GroupName : %";
        c.Series[0].ValueMembersY = "% of Total LineCount";
        c.Series[0].Type = SeriesChartType.Pie;
        c.Series[0]["PieLabelStyle"] = "Inside";
        c.Series[0]["PieDrawingStyle"] = "SoftEdge";
        c.Series[0].ShowInLegend = false;
        c.DataBind();
        //Chart Title
        c.Palette = ChartColorPalette.Dundas;
        c.Titles.Clear();
        c.Titles.Add("PDSL Major & Minor Cause Categories");
        c.Titles[0].Font = new Font("Arial", 14, FontStyle.Bold);
        c.Titles.Add(Timeline10.FYRangeFrom + " - " + Timeline10.FYRangeTo);
        c.Titles[1].Font = new Font("Arial", 8, FontStyle.Regular);
        c.ChartAreas[0].Area3DStyle.Enable3D = true;
        c.ChartAreas[0].Area3DStyle.XAngle = 5;
