C#.net使用DotNetCharting控件生成报表统计图--A

2009-09-05 20:11 776 查看
在做项目时要对数据进行统计分析,所以必须生成一些报表统计图(如柱形图、饼图、曲线图等),网上强烈推荐了使用DotNetCharting控件来实现,于是自己对DotNetCharting控件进行了简单的学习,下面先简单介绍一下DotNetCharting控件及其使用。

DotNetCharting是一个非常棒的.NET图表控件,对中文支持非常好,而且操作方便,开发快速,既有for webform 也有for winform的,而且.net1.1和2.0都有支持。它的官方地址是http://www.dotnetcharting.com/

本站也提供了DotNetCharting破解版本下载: http://files.cnblogs.com/dreamof/dotnetcharting.rar

强烈推荐一下DotNetCharting的demo地址:
这个是所有的 DEMO 演示 http://www.dotnetcharting.com/demo.aspx 这个是 Online Documentation http://www.dotnetcharting.com/documentation/v4_4/webframe.html 里面会有详细的说明和用法。

DotNetCharting的简单使用方法:
1.把/bin/dotnetCHARTING.dll添加到工具箱,并且添加引用;

2.把控件拖到你的网页上,然后添加引用using dotnetCHARTING;就可以用了;

3.接下来是自己写的对DotNetCharting操作的封装类,以便于在程序里调用。

效果图展示:
1、饼图



2、柱形图



3、曲线图



补充:
帖子发了一天,没人回答我多维统计图的实现方式,只好自己去dotnetcharting的官方网站下载了最新的dotnetcharting控件,在 dotnetcharting控件的使用说明文档中详细地介绍了各种多维统计图的实现方式。现把说明文档贴出来供大家下载
dotnetcharting使用说明文档

追加补充新内容:
1、解决“每运行一次DotNetCharting页面,就会生成一个图片,这样图片不是越来越多吗?请问怎样自动删除DotNetCharting生成的图片呢”的问题,参照asp.net删除文件夹里的所有文件

2、解决“(1)生成的图片带超链接导向官网,如何处理呀?(2)我使用这个控件后,图形可以显示出来。但是发现一个小问题。就是在图形的左上方和图形的下面都隐含了超链接,鼠标移动到这两个区域后,点击都会链接到http://www.dotnetcharting.com/。很奇怪,这是和破解有管吗?”等类似的问题,参照DotnetCharting控件各版本破解方法
