asp.net中对amCharts(.net版)图形报表的使用

先来看看几个实现的

1.饼图

2.柱型图

3.线型图

 

第一步

当然是要添加dll引用

然后再把相关文件放到目录里

就像在项目里添加FCK编辑器一样

这样的话.开始的环境就好了

我的目录结构是这样的

当然只是为了测试,就没有那样去什么什么了
当然,在每个页的开始要注册一下这个dll
<%@ Register Assembly="am.Charts" Namespace="am.Charts" TagPrefix="cc1" %>
然后就可以用了
饼图
<cc1:PieChart runat="server" ID="PieChart1"></cc1:PieChart>
后台代码

protected void Page_Load(object sender, EventArgs e)
        {
            for (int i = 0; i < 10; i++)
            {
                //PieChartDataItem pcd = new PieChartDataItem("刘巨" + i.ToString(), i);
                PieChartDataItem pcd1 = new PieChartDataItem();
                pcd1.Description = "Description" + i.ToString();
                pcd1.Title = "刘巨" + i.ToString();
                //设置点击时候的链接
                //pcd1.Url = "http://www.cnblogs.com/liuju150/";
                pcd1.LabelRadius = 1;
                pcd1.Value = i;
                pcd1.PullOut = true;
                PieChart1.Items.Add(pcd1);
            }
            PieChart1.Width = 600;
            PieChart1.Height = 500;
            //设置链接的跳转方式
            //PieChart1.SliceLinkTarget = "_blank";
            PieChart1.ScientificMax = 20;
            PieChart1.Labels.Add(new ChartLabel("测试饼图", new Unit(100), new Unit(20)));
            PieChart1.ToolTip = "测试饼图2";
        }

柱型图
