本文以实例形式详细讲述了dotnetcharting控件的用法。分享给大家供大家参考。具体用法分析如下：
dotnetcharting 是一个很好用的图表控件，能画出很漂亮的报表，一般常用到的主要有柱状图、饼图、折线图三种。
dotnetcharting 有web版、winform版多个版本可供使用，官方网址：http://www.dotnetcharting.com/ ，官网有很多示例（http://www.dotnetcharting.com/gallery/），而且有winform安装版示例和代码，如下图。
dotnetcharting 有网上破解版的，去百度或谷歌一搜一堆。
说下个人感受，该控件是国外开发的，虽然说这个控件挺好用的，但是感觉这个控件应该在有xp系统的时候就应该有了吧？是国外剩下的技术，咱们一直在用别人不用的技术，捧为珍宝。
有些技术有些人，有些本事就开始自大起来，小有成就的那点技术还藏着掖着。 呵呵。。。
接下来上干货，前两天刚使用dotnetcharting 做了个统计报表，代码如下：
using System.Collections.Generic;
using System.Data;
using System.Drawing;
using dotnetCHARTING.WinForms;
using StationChart.Model;
using StationChart.Utility;
using Chart = dotnetCHARTING.WinForms.Chart;
using Series = dotnetCHARTING.WinForms.Series;
using SeriesCollection = dotnetCHARTING.WinForms.SeriesCollection;
