推荐答案

如果你在标记中声明这样的普通asp.net图表......

If you declare a normal asp.net Chart like this in your markup...

<asp:Chart ID="Chart1" runat="server" Height="600px" Width="900px">
                <Series>
                    <asp:Series Name="Series1" IsValueShownAsLabel="true"></asp:Series>
                </Series>
                <ChartAreas>
                    <asp:ChartArea Name="caMain">
                        <Area3DStyle IsClustered="true" Enable3D="True" />
                        <AxisX>
                            <LabelStyle Interval="1" />
                        </AxisX>
                    </asp:ChartArea>
                </ChartAreas>
            </asp:Chart>

那么你可以通过从数据库中获取DataTable来直接添加任意数量的列，其中第一列是您的x轴标签，第二列是您的数据点，因此您的表将会看起来像这样...

然后当你绑定图表时，你可以做这样的事情...

then you could dymanically add as many columns as you wish by just getting a DataTable from your database where the first column is your x-axis labels and your second column is your data points, so your table will look something like this...

Column A Column B

Then when you bind the chart you could just do something like this...

Chart1.Titles.Add("Your Chart Description");
        Chart1.Series["Series1"].Points.Clear();
        foreach (DataRow r in dtReport.Rows)
                Chart1.Series["Series1"].Points.AddXY(r[0].ToString(), r[1].ToString());

希望这有帮助......
