如何編寫asp.net中調(diào)用Office來制作3D統(tǒng)計(jì)圖的代碼

發(fā)布時(shí)間:2021-10-08 16:29:28 來源:億速云 閱讀:117 作者:iii 欄目:開發(fā)技術(shù)

這篇文章主要講解了“如何編寫asp.net中調(diào)用Office來制作3D統(tǒng)計(jì)圖的代碼”,文中的講解內(nèi)容簡單清晰,易于學(xué)習(xí)與理解,下面請(qǐng)大家跟著小編的思路慢慢深入,一起來研究和學(xué)習(xí)“如何編寫asp.net中調(diào)用Office來制作3D統(tǒng)計(jì)圖的代碼”吧!

1、首先下載owc11 COM組件

http://www.microsoft.com/downloads/details.aspx?FamilyID=7287252c-402e-4f72-97a5-e0fd290d4b76&displaylang=en

2、注冊(cè)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:

復(fù)制代碼 代碼如下:

   public class ChartFactory
  {
  public ChartFactory()
  {
  InitTypeMap();
  //
  // TODO: 在此處添加構(gòu)造函數(shù)邏輯
  //
  }
  protected System.Web.UI.WebControls.Image imgHondaLineup;
  private string[] chartCategoriesArr;
  private string[] chartValuesArr;
  private OWC11.ChartChartTypeEnum chartType =  OWC11.ChartChartTypeEnum.chChartTypeColumn3D;//默認(rèn)值
  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.chChartTypeBarClustered,
  ChartChartTypeEnum.chChartTypeBar3D,

  ChartChartTypeEnum.chChartTypeArea3D,
  ChartChartTypeEnum.chChartTypeDoughnut,
  ChartChartTypeEnum.chChartTypeLineStacked,
  ChartChartTypeEnum.chChartTypeLine3D,
  ChartChartTypeEnum.chChartTypeLineMarkers,
  ChartChartTypeEnum.chChartTypePie,
  ChartChartTypeEnum.chChartTypePie3D,
   ChartChartTypeEnum.chChartTypeRadarSmoothLine,
  ChartChartTypeEnum.chChartTypeSmoothLine};

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


   for(int i=0;i<chartTypes.Length;i++)
