2、注册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 或者按如下图所以添加com
3、在工程中添加
using OWC11;
4、开始coding 举例如下：
public class ChartFactory
{
public ChartFactory()
{
InitTypeMap();
//
// TODO: 在此处添加构造函数逻辑
//
}
protected System.Web.UI.WebControls.Image imgHondaLineup;
private string[] chartCategoriesArr;
private string[] chartValuesArr;
private OWC11.ChartChartTypeEnum chartType = OWC11.ChartChartTypeEnum.chChartTypeColumn3D;//默认值
private static Hashtable chartMap = new Hashtable();
private static string chartTypeCh = "垂直柱状图" ;
private static string chartTitle = "";
private void InitTypeMap()
{
chartMap.Clear();
OWC11.ChartChartTypeEnum[] chartTypes = new OWC11.ChartChartTypeEnum[]{ ChartChartTypeEnum.chChartTypeColumnClustered,
ChartChartTypeEnum.chChartTypeColumn3D,

ChartChartTypeEnum.chChartTypeArea3D,
ChartChartTypeEnum.chChartTypeDoughnut,
ChartChartTypeEnum.chChartTypeLineStacked,
ChartChartTypeEnum.chChartTypeLine3D,
ChartChartTypeEnum.chChartTypeLineMarkers,
ChartChartTypeEnum.chChartTypePie,
ChartChartTypeEnum.chChartTypePie3D,
ChartChartTypeEnum.chChartTypeRadarSmoothLine,
ChartChartTypeEnum.chChartTypeSmoothLine};
string[] chartTypesCh = new string [] {"垂直柱状统计图","3D垂直柱状统计图","水平柱状统计图","3D水平柱状统计图","区域统计图","3D区域统计图","中空饼图","折线统计图","3D折线统计图","折线带点统计图","饼图","3D饼图","网状统计图","弧线统计图"};
