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:
1 <asp:Chart ID="Chart1" runat="server" Width="627px"> 2 <Legends> 3 <asp:Legend></asp:Legend> 4 </Legends> 5 <Titles> 6 <asp:Title Text="测试趋势图"></asp:Title> 7 </Titles> 8 <Series> 9 <asp:Series Name="Series1" LegendText="测试1" ChartType="Line" Label="#VAL" 10 MarkerStyle="Square" LabelToolTip="#VAL" YValuesPerPoint="6"></asp:Series> 11 <asp:Series Name="" LegendText="测试2" ChartType="Line" Label="#VAL" 12 MarkerStyle="Circle" LabelToolTip="#VAL" YValuesPerPoint="6"></asp:Series> 13 </Series> 14 <ChartAreas> 15 <asp:ChartArea Name="ChartArea1" ShadowOffset="4"> 16 <AxisY LineColor="64, 64, 64, 64" Title="评分分数" LineWidth="2"> 17 <LabelStyle Font="Trebuchet MS, 8.25pt, style=Bold" /> 18 <MajorGrid LineColor="64, 64, 64, 64" /> 19 </AxisY> 20 </asp:ChartArea> 21 </ChartAreas> 22 </asp:Chart>
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:
后台绑定代码:
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!!
