ASP.Net中的餅圖，條形圖

Question

我想在我的asp.net應用程序中繪製餅圖和條形圖以詳細顯示年度報告。有沒有免費的工具可用於此？

我已經看到從森林主題的白色標籤主題圖，但這些是付費版本。

餅圖例如：

<%@ Page language="c#" debug="true" %> 
<%@ import Namespace = "csASPNetGraph" %> 
<% 
Response.Buffer = true; 
Response.Expires = 0; 
Response.Clear(); 
GraphClass Graph = new GraphClass(); 
Graph.Title = "Pie Chart Example"; 
Graph.AddData("Item 1", 17, "ff0000"); 
Graph.AddData("Item 2", 28, "00ff00"); 
Graph.AddData("Item 3", 5, "0000ff"); 
Graph.GraphType = 0; 
Graph.GraphToBrowser(1); 
%> 

條形圖例如：

<%@ Page language="c#" debug="true" %> 
    <%@ import Namespace = "csASPNetGraph" %> 
    <% 
    Response.Buffer = true; 
    Response.Expires = 0; 
    Response.Clear(); 
    GraphClass Graph = new GraphClass(); 
    Graph.Title = "Bar Chart Example"; 
    Graph.TitleX = 120; 
    Graph.ShowBarTotal = true; 
    Graph.AddData("Item 1", 17, "ff0000"); 
    Graph.AddData("Item 2", 28, "00ff00"); 
    Graph.AddData("Item 3", 5, "0000ff"); 
    Graph.GraphType = 1; 
    Graph.GraphToBrowser(1); 
    %>

在ASP.NET 4.0及更高版本，還有一個內置的圖表控件，它可以在ASP.NET 3.5 SP1單獨下載。

您可以將圖表（<asp:Chart>）控件從工具箱的Data部分拖動到.aspx頁面上。
