最近用到统计方面的功能,文档统计不用说,都是导出Excel,若要视图效果,这里推荐一个Asp.NET中的控件Char。
简单示例:
视图显示说明:
可以设定Series的ChartType属性值,来决定显示什么样的视图,下面是常用的视图举例:

protected void Page_Load( object sender, EventArgs e)
{
DataTable dt = default (DataTable);
dt = CreateDataTable();
//设置图表的数据源
Chart1.DataSource = dt;
//设置图表Y轴对应项
Chart1.Series[0].YValueMembers = "Volume1" ;
Chart1.Series[1].YValueMembers = "Volume2" ;
//设置图表X轴对应项
Chart1.Series[0].XValueMember = "Date" ;
//绑定数据
Chart1.DataBind();
}
private DataTable CreateDataTable()
{
//Create a DataTable as the data source of the Chart control
DataTable dt = new DataTable();
//Add three columns to the DataTable
dt.Columns.Add( "Date" );
dt.Columns.Add( "Volume1" );
dt.Columns.Add( "Volume2" );
DataRow dr;
//Add rows to the table which contains some random data for demonstration
dr = dt.NewRow();
dr[ "Date" ] = "Jan" ;
dr[ "Volume1" ] = 3731;
dr[ "Volume2" ] = 4101;
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[ "Date" ] = "Feb" ;
dr[ "Volume1" ] = 6024;
dr[ "Volume2" ] = 4324;
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[ "Date" ] = "Mar" ;
dr[ "Volume1" ] = 4935;
dr[ "Volume2" ] = 2935;
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[ "Date" ] = "Apr" ;
dr[ "Volume1" ] = 4466;
dr[ "Volume2" ] = 5644;
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[ "Date" ] = "May" ;
dr[ "Volume1" ] = 5117;
dr[ "Volume2" ] = 5671;
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[ "Date" ] = "Jun" ;
dr[ "Volume1" ] = 3546;
dr[ "Volume2" ] = 4646;
dt.Rows.Add(dr);
return dt;
}

显示结果以柱状图为例,如下:
这是本人初次使用Char控件的学习笔记,不喜勿喷,谢谢!!
