请问如何把统计直方图程序改造成统计直方图程序？
我有一段利用OWC画直方图的程序如下。现想改造成画曲线图的程序。不知道如何改造，特此请教。谢谢！using System;

--------------------编程问答-------------------- objChart.Type = ChartChartTypeEnum.chChartTypeBarClustered;
改成:
objChart.Type = Microsoft.Office.Interop.Owc11.ChartChartTypeEnum.chChartTypeLine;
ChartChartTypeEnum有很多类型.你可以都试试..呵呵. --------------------编程问答-------------------- 另外b/s结构.string str = "c:\\xyz.gif";
最好不要直接引用图片..这样会有一个问题.好好想想吧..就是在多个人一起看图片..生成图片的时候.
会冲突的!
--------------------编程问答-------------------- 谢谢lovehongyun。如果不直接引用图片，还真不知道objCSpace.ExportPicture(str, "gif", 500, 500)中的str能填写成文件路径外的其他什么值。恳请继续赐教。多谢了！ --------------------编程问答--------------------
补充：.NET技术 , ASP.NET
