VS2010学习:Chart控件

     VS2010新增Chart控件，可以直接在页面插入图表：

    

     简单示例：

   <asp:Chart ID="Chart1" runat="server" Height="400px" Width="500px">
            <Series>
                <asp:Series Name="Series1" ChartType="Column" ChartArea="ChartArea1">
                </asp:Series>
                <asp:Series Name="Series2" ChartType="Column" ChartArea="ChartArea1">
                </asp:Series>
            </Series>
            <ChartAreas>
                <asp:ChartArea Name="ChartArea1">
                </asp:ChartArea>
            </ChartAreas>
      </asp:Chart>

   后台代码：

   protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = default(DataTable);
            dt = CreateDataTable();

            //设置图表的数据源
            Chart1.DataSource = dt;

            //设置图表Y轴对应项
            Chart1.Series[0].YValueMembers = "Volume1";
            Chart1.Series[1].YValueMembers = "Volume2";

            //设置图表X轴对应项
            Chart1.Series[0].XValueMember = "Date";
            
            //绑定数据
            Chart1.DataBind();
        }

        private DataTable CreateDataTable()
        {
            //Create a DataTable as the data source of the Chart control
            DataTable dt = new DataTable();

            //Add three columns to the DataTable
            dt.Columns.Add("Date");
            dt.Columns.Add("Volume1");
            dt.Columns.Add("Volume2");

            DataRow dr;

            //Add rows to the table which contains some random data for demonstration
            dr = dt.NewRow();
            dr["Date"] = "Jan";
            dr["Volume1"] = 3731;
            dr["Volume2"] = 4101;
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["Date"] = "Feb";
            dr["Volume1"] = 6024;
            dr["Volume2"] = 4324;
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["Date"] = "Mar";
            dr["Volume1"] = 4935;
            dr["Volume2"] = 2935;
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["Date"] = "Apr";
            dr["Volume1"] = 4466;
            dr["Volume2"] = 5644;
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["Date"] = "May";
            dr["Volume1"] = 5117;
            dr["Volume2"] = 5671;
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["Date"] = "Jun";
            dr["Volume1"] = 3546;
            dr["Volume2"] = 4646;
            dt.Rows.Add(dr);

            return dt;
        }
