FusionCharts 统计 几种实例用法

 今天加班文档整理完写下这篇博客，不好的地方大家提提意见。 我也是新手啊。

  下面我先发一个3D柱形统计图

  首先 把数据库代码发上来省的大家建表

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[AAAAgrade]') AND type in (N'U'))
BEGIN
CREATE TABLE [dbo].[AAAAgrade](
	[name] [varchar](50) NULL,
	[id] [int] NOT NULL,
	[grade] [int] NULL,
	[source] [int] NULL,
 CONSTRAINT [PK_AAAAgrade] PRIMARY KEY CLUSTERED 
(
	[id] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
END

第一步：先把 <asp:Literal ID="Literal1" runat="server"></asp:Literal> 拖入前端页面
第二步： 后台代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using InfoSoftGlobal;

namespace Statistics
{
    public partial class Default : System.Web.UI.Page
    {

        private string conectionString = System.Configuration.ConfigurationManager.ConnectionStrings["Charts"].ConnectionString;
        protected void Page_Load(object sender, EventArgs e)
        {
            this.Literal1.Text = GetGradeStat();
        }
            /// <summary>
        ///  根据xml格式把数据显示到页面
        /// </summary>
        /// <returns></returns>
        public string GetGradeStat()
        {
            string strXML;
            strXML = "<graph caption='考试分数对比' xAxisName='姓名' yAxisName='成绩' decimalPrecision='0' formatNumberScale='1'  palette='4'>";
            //strXML = strXML + "<categories>";
            //name表数据
            SqlConnection con = new SqlConnection(conectionString);
            con.Open();
            SqlDataAdapter adapter = new SqlDataAdapter("select name from AAAAgrade",con);
            DataSet ds = new DataSet();
            adapter.Fill(ds,"name");
            DataTable dt = ds.Tables["name"];
            //grade表数据
            SqlDataAdapter adapter1 = new SqlDataAdapter("select grade from AAAAgrade", con);
            adapter1.Fill(ds, "grade");
            DataTable dt2 = ds.Tables["grade"];
            //for (int j = 0; j < dt2.Rows.Count; j++)
            //{
            //    strXML = strXML + "<set value='" + dt2.Rows[j][0].ToString() + "'/>";
            //}


            for (int i = 0; i < dt.Rows.Count; i++)
            {
                strXML = strXML + "<set name='" + dt.Rows[i][0].ToString() + "' value='" + dt2.Rows[i][0].ToString() + "' />";
            }
            //strXML = strXML + "</categories> ";
          
         
            strXML = strXML + "</graph>";
            return FusionCharts.RenderChart("FusionCharts/Column3D.swf", "Default.aspx", strXML, "myNext", "750", "300", false, false);
          
        }
    }
}

　　如下图柱形

这就完成了柱形统计》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》。。。

 二、、

在发给双线图  首先前端还是微软的Literal控件

然后后端代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using InfoSoftGlobal;

namespace Statistics
{
    public partial class Default4 : System.Web.UI.Page
    {

        private string conectionString = System.Configuration.ConfigurationManager.ConnectionStrings["Charts"].ConnectionString;
        protected void Page_Load(object sender, EventArgs e)
        {
            this.Literal1.Text = GetGradeStat();
        }
        /// <summary>
        ///  根据xml格式把数据显示到页面
        /// </summary>
        /// <returns></returns>
         public string GetGradeStat()
        {
            string strXML;
            strXML = "<chart  caption='考试分数对比' xAxisName='姓名' yAxisName='成绩' decimalPrecision='0' formatNumberScale='1'  palette='4'  showLabels='1' showColumnShadow='1' animation='1' showAlternateHGridColor='1' AlternateHGridColor='ff5904' divLineColor='ff5904' divLineAlpha='20' alternateHGridAlpha='5' canvasBorderColor='666666' baseFontColor='666666' lineColor='FF5904' lineAlpha='85' showValues='1' rotateValues='1' valuePosition='auto' canvaspadding='8'>";
            strXML = strXML + "<categories>";
            //name字段数据
            SqlConnection con = new SqlConnection(conectionString);
            con.Open();
            SqlDataAdapter adapter = new SqlDataAdapter("select name from AAAAgrade", con);
            DataSet ds = new DataSet();
            adapter.Fill(ds, "name");
            DataTable dt = ds.Tables["name"];

            for (int i = 0; i < dt.Rows.Count; i++)
            {
                strXML = strXML + "<category label='" + dt.Rows[i][0].ToString() + "'  isSliced='0'/>";
            }
            strXML = strXML + "</categories><dataset seriesName='Model A12' color='A66EDD' > ";
            //grade字段数据
            SqlDataAdapter adapter1 = new SqlDataAdapter("select grade from AAAAgrade", con);
            adapter1.Fill(ds, "grade");
            DataTable dt2 = ds.Tables["grade"];
            for (int j = 0; j < dt2.Rows.Count; j++)
            {
                strXML = strXML + "<set value='" + dt2.Rows[j][0].ToString() + "'/>";
            }

            strXML = strXML + "</dataset><dataset seriesName='Model A15' color='F6BD0F'>";
            //source字段数据
            SqlDataAdapter adapter2 = new SqlDataAdapter("select source from AAAAgrade", con);
            adapter2.Fill(ds, "source");
            DataTable dt3 = ds.Tables["source"];
            for (int d = 0; d< dt3.Rows.Count; d++)
            {
                strXML = strXML + "<set value='" + dt3.Rows[d][0].ToString() + "'/>";
            }
            strXML = strXML + "</dataset>";
            strXML = strXML + "</chart>";
            return FusionCharts.RenderChart("FusionCharts/MSLine.swf", "Default.aspx", strXML, "myNext", "750", "300", false, false);

        }
    }
}

　　如下图

其它数据统计可以下载FusionCharts 就可以完成呢。。。。。。。。。
