RangeBar Chart Type in ASP.Net

Background
 
ASP.Net Chart is a powerful control for creating interactive charts to show a wide range of information. RangeBar is one of the chart types for showing how the data is increasing or decreasing . So today we will discuss the Range chart type of ASP.Net. So let us start to learn about this chart type control step-by-step.

Let us explain it with a practical example by creating a simple web application.

Step 1
 
Use the following script to create and insert data into the table for the chart:
  1. SET ANSI_NULLS ON            
  2. GO            
  3. SET QUOTED_IDENTIFIER ON            
  4. GO            
  5. SET ANSI_PADDING ON            
  6. GO            
  7. CREATE TABLE [dbo].[orderdet](            
  8.     [id] [int] IDENTITY(1,1) NOT NULL,            
  9.     [Month] [varchar](50) NULL,            
  10.     [Orders] [intNULL,            
  11.  CONSTRAINT [PK_Order TablePRIMARY KEY CLUSTERED             
  12. (            
  13.     [id] ASC            
  14. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ONON [PRIMARY]            
  15. ON [PRIMARY]            
  16.             
  17. GO            
  18. SET ANSI_PADDING OFF            
  19. GO            
  20. SET IDENTITY_INSERT [dbo].[orderdet] ON             
  21.             
  22. GO            
  23. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (1, N'Jan', 0)            
  24. GO            
  25. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (2, N'Feb', 5)            
  26. GO            
  27. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (3, N'March', 20)            
  28. GO            
  29. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (4, N'April', 40)            
  30. GO            
  31. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (5, N'May', 15)            
  32. GO            
  33. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (6, N'Jun', 60)            
  34. GO            
  35. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (7, N'July', 75)            
  36. GO            
  37. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (8, N'Aug', 80)            
  38. GO            
  39. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (9, N'Sep', 85)            
  40. GO            
  41. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (10, N'Oct', 100)            
  42. GO            
  43. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (11, N'Nov', 2)            
  44. GO            
  45. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (12, N'Dec', 90)            
  46. GO            
  47. SET IDENTITY_INSERT [dbo].[orderdet] OFF            
  48. Go         
 After running the preceding script the records in the table will look as follows:
 
 
Step 2

Create a Stored Procedure to fetch the records from the database.
  1. Create procedure [dbo].[GetCharData]          
  2. (          
  3. @id int =null          
  4.           
  5. )          
  6. as          
  7. begin          
  8. Select Month,Orders from Orderdet          
  9. End     
Step 3

Create a Web Application. Create the website with:
  1. "Start" - "All Programs" - "Microsoft Visual Studio 2010".

  2. "File" - "New Project" - "C#" - "Empty Website" (to avoid adding a master page).

  3. Provide the project a name such as "UsingRangeBarChart" or another as you wish and specify the location.

  4. Then right-click on the Solution Explorer and select "Add New Item" then select Default.aspx page.

  5. Drag and Drop a Chart control from the ToolBox onto the Default.aspx page.
Now the Default.aspx source code will be as follows:
  1. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>  
  2.   
  3. <%@ Register Assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"  
  4.     Namespace="System.Web.UI.DataVisualization.Charting" TagPrefix="asp" %>  
  5. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">  
  6. <html xmlns="http://www.w3.org/1999/xhtml">  
  7. <head runat="server">  
  8.     <title>Article by Vithal Wadje</title>  
  9. </head>  
  10. <body bgcolor="Navy">  
  11.     <form id="form1" runat="server">  
  12.     <h4 style="color: White;">  
  13.         Article for C#Corner  
  14.     </h4>  
  15.     <asp:Chart ID="Chart1" runat="server" BackColor="64, 0, 0" BackGradientStyle="LeftRight"  
  16.         BorderlineWidth="0" Height="360px" Palette="None" PaletteCustomColors="64, 0, 0"  
  17.         Width="380px" BorderlineColor="0, 64, 64">  
  18.         <Series>  
  19.             <asp:Series Name="Series1"  YValuesPerPoint="12">  
  20.             </asp:Series>  
  21.         </Series>  
  22.         <ChartAreas>  
  23.             <asp:ChartArea Name="ChartArea1">  
  24.             </asp:ChartArea>  
  25.         </ChartAreas>  
  26.     </asp:Chart>  
  27.     </form>  
  28. </body>  
  29. </html> 
Step 4

Create a method to bind the chart control. Then open the default.aspx.cs page and create the following function named Bindchart to bind the Chart Control as in the following:
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.UI;  
  6. using System.Web.UI.WebControls;  
  7. using System.Data.SqlClient;  
  8. using System.Configuration;  
  9. using System.Data;  
  10. using System.Web.UI.DataVisualization.Charting;  
  11.   
  12. public partial class _Default : System.Web.UI.Page  
  13. {  
  14.     private SqlConnection con;  
  15.     private SqlCommand com;  
  16.     private string constr, query;  
  17.     private void connection()  
  18.     {  
  19.         constr = ConfigurationManager.ConnectionStrings["getconn"].ToString();  
  20.         con = new SqlConnection(constr);  
  21.         con.Open();  
  22.   
  23.     }  
  24.     protected void Page_Load(object sender, EventArgs e)  
  25.     {  
  26.         if (!IsPostBack)  
  27.         {  
  28.             Bindchart();  
  29.   
  30.         }  
  31.     }  
  32.   
  33.   
  34.     private void Bindchart()  
  35.     {  
  36.         connection();  
  37.         com = new SqlCommand("GetCharData", con);  
  38.         com.CommandType = CommandType.StoredProcedure;  
  39.         SqlDataAdapter da = new SqlDataAdapter(com);  
  40.         DataSet ds = new DataSet();  
  41.         da.Fill(ds);  
  42.   
  43.         DataTable ChartData = ds.Tables[0];  
  44.   
  45.         //storing total rows count to loop on each Record  
  46.         string[] XPointMember = new string[ChartData.Rows.Count];  
  47.         int[] YPointMember = new int[ChartData.Rows.Count];  
  48.   
  49.         for (int count = 0; count < ChartData.Rows.Count; count++)  
  50.         {  
  51.             //storing Values for X axis  
  52.             XPointMember[count] = ChartData.Rows[count]["Month"].ToString();  
  53.             //storing values for Y Axis  
  54.             YPointMember[count] = Convert.ToInt32(ChartData.Rows[count]["Orders"]);  
  55.   
  56.   
  57.         }  
  58.         //binding chart control  
  59.         Chart1.Series[0].Points.DataBindXY(XPointMember, YPointMember);  
  60.   
  61.         //Setting width of line  
  62.         Chart1.Series[0].BorderWidth = 4;  
  63.         //setting Chart type   
  64.         Chart1.Series[0].ChartType = SeriesChartType.RangeBar;  
  65.        
  66.         //Hide or show chart back GridLines  
  67.  // Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;  
  68.    //Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;  
  69.   
  70.         //Enabled 3D  
  71.        //Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;  
  72.         con.Close();  
  73.   
  74.     }  

Now, call the preceding function on page load as in the following:
  1. protected void Page_Load(object sender, EventArgs e)        
  2.     {        
  3.         if (!IsPostBack)        
  4.         {        
  5.             Bindchart();        
  6.         
  7.         }        
  8.     }      
 The entire code of the default.aspx.cs page will look as follows:
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.UI;  
  6. using System.Web.UI.WebControls;  
  7. using System.Data.SqlClient;  
  8. using System.Configuration;  
  9. using System.Data;  
  10. using System.Web.UI.DataVisualization.Charting;  
  11.   
  12. public partial class _Default : System.Web.UI.Page  
  13. {  
  14.     private SqlConnection con;  
  15.     private SqlCommand com;  
  16.     private string constr, query;  
  17.     private void connection()  
  18.     {  
  19.         constr = ConfigurationManager.ConnectionStrings["getconn"].ToString();  
  20.         con = new SqlConnection(constr);  
  21.         con.Open();  
  22.   
  23.     }  
  24.     protected void Page_Load(object sender, EventArgs e)  
  25.     {  
  26.         if (!IsPostBack)  
  27.         {  
  28.             Bindchart();  
  29.   
  30.         }  
  31.     }   
  32.     private void Bindchart()  
  33.     {  
  34.         connection();  
  35.         com = new SqlCommand("GetCharData", con);  
  36.         com.CommandType = CommandType.StoredProcedure;  
  37.         SqlDataAdapter da = new SqlDataAdapter(com);  
  38.         DataSet ds = new DataSet();  
  39.         da.Fill(ds);  
  40.   
  41.         DataTable ChartData = ds.Tables[0];  
  42.   
  43.         //storing total rows count to loop on each Record  
  44.         string[] XPointMember = new string[ChartData.Rows.Count];  
  45.         int[] YPointMember = new int[ChartData.Rows.Count];  
  46.   
  47.         for (int count = 0; count < ChartData.Rows.Count; count++)  
  48.         {  
  49.             //storing Values for X axis  
  50.             XPointMember[count] = ChartData.Rows[count]["Month"].ToString();  
  51.             //storing values for Y Axis  
  52.             YPointMember[count] = Convert.ToInt32(ChartData.Rows[count]["Orders"]);  
  53.   
  54.   
  55.         }  
  56.         //binding chart control  
  57.         Chart1.Series[0].Points.DataBindXY(XPointMember, YPointMember);  
  58.   
  59.         //Setting width of line  
  60.         Chart1.Series[0].BorderWidth = 4;  
  61.         //setting Chart type   
  62.         Chart1.Series[0].ChartType = SeriesChartType.RangeBar;  
  63.        
  64.         //Hide or show chart back GridLines  
  65.  // Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;  
  66.    //Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;  
  67.   
  68.         //Enabled 3D  
  69.        //Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;  
  70.         con.Close();  
  71.   
  72.     }  

Now, we have the entire logic to bind the chart from the database, let us run the application. The RangeBar Chart will look as follows:
 
 
Now hide the chart Grid Lines as:
  1. //Hide or show chart back GridLines        
  2. Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;        
  3. Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;  
Then the RangeBar chart will look as follows:

 
 
Now enable the 3D Style as in the following:
  1. //Enabled 3D        
  2.  Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;      
Now run the application then the RangeBar Chart will look as follows:
 
 
Now let us hide the GridLines in 3D Style Mode as:
  1. //Hide or show chart back GridLines        
  2. Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;        
  3. Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;   
 Now the RangeBar Chart will look as follows:
 
 
Now from all the preceding explanations we saw how to create and use a RangeBar chart.

Notes
  • Download the Zip file from the attachment for the full source code of the application.

  • Change the connection string in the web.config file to specify your server location.
