owc控件是microsoft office 图表控件(owc10为ofiiceXP的组件、owc11为office2003的组件,组件的路径为C:\Program Files\Common Files\Microsoft Shared\Web Components\11\owc11,帮助文件的路径为C:\Program Files\Common Files\Microsoft Shared\Web Components\11\2052),它可以生成三维图、柱状图、饼状图、趋势图和误差图,下面以生成三维图web应用程序为例:
1,添加引用:在“com选项卡”中选择“misrosoft office 11.0 object library”
2,具体代码如下:
