   1、首先下載owc11 COM組件

       [點擊下載]

  2、注冊owc11

  在工程中添加 C:\Program Files\Common Files\Microsoft Shared\Web Components\11  文件下的owc11.dll引用

  3、在工程中添加

  using OWC11;

  4、開始coding  舉例如下:


   public class ChartFactory
  {
  public ChartFactory()
  {
  InitTypeMap();
  //
  // TODO: 在此處添加構(gòu)造函數(shù)邏輯
  //

  private static Hashtable chartMap = new Hashtable();
  private static string chartTypeCh = "垂直柱狀圖" ;
  private static string chartTitle = "";

  private void InitTypeMap()
  {
  chartMap.Clear();
  OWC11.ChartChartTypeEnum[] chartTypes = new OWC11.ChartChartTypeEnum[]{ ChartChartTypeEnum.chChartTypeColumnClustered,
  ChartChartTypeEnum.chChartTypeColumn3D,

  ChartChartTypeEnum.chChartTypeBar3D,

  ChartChartTypeEnum.chChartTypeArea3D,
  ChartChartTypeEnum.chChartTypeDoughnut,

  ChartChartTypeEnum.chChartTypeLine3D,
  ChartChartTypeEnum.chChartTypeLineMarkers,
  ChartChartTypeEnum.chChartTypePie,
  ChartChartTypeEnum.chChartTypePie3D,
 

   ChartChartTypeEnum.chChartTypeRadarSmoothLine,
  ChartChartTypeEnum.chChartTypeSmoothLine};

 

  string[] chartTypesCh = new string [] {"垂直柱狀統(tǒng)計圖","3D垂直柱狀統(tǒng)計圖","水平柱狀統(tǒng)計圖","3D水平柱狀統(tǒng)計圖","區(qū)域統(tǒng)計圖","3D區(qū)域統(tǒng)計圖","中空餅圖","折線統(tǒng)計圖","3D折線統(tǒng)計圖","折線帶點統(tǒng)計圖","餅圖","3D餅圖","網(wǎng)狀統(tǒng)計圖","弧線統(tǒng)計圖"};

  // 保存統(tǒng)計圖請參照上一篇文章

  //由于每次生成的統(tǒng)計圖都會覆蓋原來的圖片所以有必要的話可以用日期加時間的方式來作為圖片的名字,但是這樣將會產(chǎn)生很多圖片需及時處理,如不需要只需取同名覆蓋原來圖片即可。
