饼图，ASP.Net中的条形图

Question

我想在我的asp.net应用程序中绘制饼图和条形图，以详细显示年度报告。是否有可用的免费工具？

我看过森林主题的白标主题图，但这些是付费版本。

Answer 1

在ASP.NET 4.0及更高版本中，有一个内置的图表控件，它可以在ASP.NET 3.5 SP1中单独下载。

您可以将图表（<asp:Chart>）控件直接从工具箱的Data部分拖到.aspx页面上。

饼图示例：

<%@ 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);
%>

条形图示例：

  <%@ 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);
    %>
