dotnetcharting 生成柱状图,饼图等统计图
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。官方地址是http://www.dotnetcharting.com/
简单使用方法:
1.首先要搞定帮助文档:从官方网站下载解压后把dotnetcharting4.2for1.x目录设置成虚拟目录,.net1.1的环境,然后就可以看帮助示例了。
2.把\bin\dotnetCHARTING.dll添加到工具箱,并且添加引用
3.把控件拖到你的网页上,然后添加引用using dotnetCHARTING;就可以用了
4.说下简单的柱状图的用法(动态获取数据):它有个type属性决定是柱状图还是饼图或是其他,设置成Combo就是柱状图;
private void Drawing(Arraylist list) { Charting show = new Charting(); show.Title = "MyChart"; show.YTitle = "Y Axis Label"; show.XTitle = "X Axis Label"; show.PicHight = 400; show.PicWidth = 400; show.SeriesName = "具体详情"; show.PhaysicalImagePath = @"~/pictrue"; //此为图片保存的路径,不存在则会无法显示(下同) show.FileName = "Combo.png"; show.Type = ChartType.Combo;//combo为柱状图,pie为饼图 show.Use3D = false; show.DataSource = GetDataSource(); show.CreateStatisticPic(this.Chart1); } private SeriesCollection GetDataSource() { SeriesCollection SC = new SeriesCollection(); Random myR = new Random(); for(int a = 0; a < 4; a++) { Series s = new Series(); s.Name = "Series " + a; for(int b = 0; b < 5; b++) { Element e = new Element(); e.Name = "E " + b; e.YValue = myR.Next(50); s.Elements.Add(e); } SC.Add(s); } }
