OWC11绘制组合图形示例
最近做项目，要求生产面积图、柱状图和线性趋势图叠加。也就是组合图形。搜遍百度，没有找到解决方案，后来自己琢磨，终于醍醐灌顶：）
现在，可以实现面积－柱状图、柱状－线图、面积－线图、多条曲线、多面积图、多柱图等等各种变态而实用的图形。要多少组数据就添加多少个OWC11.ChSeries 对象，通过设置Type来设置图形形状：）
具体实现：
一、安装office2003 ，添加如下地址中的OWC11.dll的com引用：
C:\Program Files\Common Files\Microsoft Shared\Web Components\11
二、页面中添加命名空间 using OWC11;
三、拷贝如下不完全代码到页面（请自行添加适当缺少代码，实在不行就给我发邮件吧：），调试生成，ok……
四、确保asp.net对生成的图片保存路径下的目录有写权限，否则 owcChartSpace.ExportPicture(MapPath("./")+"1233.gif","gif", 500, 300); 这行会报错的！
