1、首先下載owc11 COM組件 [點(diǎn)擊下載]
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：
public class ChartFactory
{
public ChartFactory()
{
InitTypeMap();
//
// TODO: 在此處添加構(gòu)造函數(shù)邏輯
//
}

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();
