Introduction
Today, in this blog let's
play around with one of the interesting and most useful concept in .NET.
Question: What
are charts?
In simple terms "It
enables to draw out different graphical charts and choose the appropriate one as
per the requirement".
Step 1: Create
a new WebForm project

Step 2: The
complete code WebForm1.aspx looks like this
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="ChartApp.WebForm1" %>
<%@ Register Assembly="System.Web.DataVisualization,
Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI.DataVisualization.Charting" TagPrefix="asp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD
XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Chart ID="Chart1" runat="server">
<series><asp:Series Name="Series1" IsValueShownAsLabel="true" XValueMember="FirstName" YValueMembers="Age"></asp:Series></series>
<chartareas><asp:ChartArea Name="ChartArea1"></asp:ChartArea></chartareas>
</asp:Chart></div>
</form>
</body>
</html>
Step 3: The
complete code WebForm1.aspx.cs looks like this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
namespace ChartApp
{
public partial class WebForm1 :
System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
getData();
}
}
private void getData()
{
SqlConnection con
= new SqlConnection(@"Data
Source=WIN-KV3BO1RQQF7;Initial Catalog=Company;Integrated Security=True");
SqlDataAdapter da
= new SqlDataAdapter("Select
FirstName, Age from Employee", con);
DataSet ds
= new DataSet();
da.Fill(ds);
Chart1.DataSource = ds;
Chart1.DataBind();
}
}
}
Step 4: The
output of application looks like this
