我有以下数据集：

NAME | GP   | ORD_GP | EXP   | TOTAL GP | TARGET
a      206     48      -239     15         1600
b      0       27       0        27        1520

我正试图使用以下代码在图表中显示这一点，我只想显示NAME TOTAL_GP和TARGET:

    Chart1.Width=600;
    Chart1.BackColor = Color.Gray;
    Chart1.BackSecondaryColor = Color.WhiteSmoke;
    Chart1.BackGradientStyle = GradientStyle.DiagonalRight;
    Chart1.BorderlineDashStyle = ChartDashStyle.Solid;
    Chart1.BorderlineColor = Color.Gray;
    Chart1.BorderSkin.SkinStyle = BorderSkinStyle.Emboss;
    // format the chart area
    Chart1.ChartAreas[0].BackColor = Color.Wheat;
    // add and format the title
    Chart1.Titles.Add("ASP.NET Chart");
    Chart1.Titles[0].Font = new Font("Utopia", 16);
    // clear the chart series and bind to the table
    Chart1.DataSource = ds.Tables[0];
    Chart1.Series[0].XValueMember = "NAME";
    Chart1.Series[0].YValueMembers = "TOTAL_GP";
    Chart1.Series[0].ChartType = SeriesChartType.StackedBar;

但我总是犯错误。请你就我可能做错了什么提出建议。错误如下

Exception Details: System.ArgumentOutOfRangeException: Index was out of range. 
Must be non-negative and less than the size of the collection.
parameter name: index

更新

我在.aspx文件中有以下内容

 <asp:Chart ID="Chart1" runat="server">
        <ChartAreas>
            <asp:ChartArea Name="ChartArea1" />
        </ChartAreas>
    </asp:Chart>

解决了这个问题，不得不将.aspx文件更改为

<asp:Chart ID="Chart1" runat="server">
    <Series>
        <asp:Series Name="Series1">
        </asp:Series>
    </Series>
    <ChartAreas>
        <asp:ChartArea Name="ChartArea1">
        </asp:ChartArea>
    </ChartAreas>
</asp:Chart>
