MSChart柱圖曲線圖等實現總結及封裝

.NET4.0已經包含了MsChart了，根據自己的使用簡單介紹下，希望對網友有協助

1、web.config配置

需要在<appSettings>中增加

    <!--分析圖片 參數設定-->
    <add key="ChartImageHandler" value="storage=file;timeout=20;dir=C:\Windows\temp;"/>

在<system.webServer>中增加
    <handlers>
      <remove name="ChartImageHandler"/>
      <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,POST,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </handlers>
2、mschat實現封裝實現代碼

        /// <summary>
        /// 獲得繪圖物件
        /// </summary>
        /// <param name="page">頁面執行個體</param>
        /// <returns></returns>
        public Chart GetChart(Page page)
        {
            Chart result = new Chart();
            //映像屬性

3、產生並添加到介面

myChart.DataSource = dv;//支援DataSet DataTable DataView 或者對象集合（程式中使用反射獲得資料）
divChart2.Controls.Add(myChart.GetChart(Page));
