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.     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.         //binding chart control  
  55.         Chart1.Series[0].Points.DataBindXY(XPointMember, YPointMember);  
  56.   
  57.         //Setting width of line  
  58.         Chart1.Series[0].BorderWidth = 4;  
  59.         //setting Chart type   
  60.         Chart1.Series[0].ChartType = SeriesChartType.RangeBar;  
  61.        
  62.         //Hide or show chart back GridLines  
  63.         // Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;  
  64.         //Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;  
  65.   
  66.         //Enabled 3D  
  67.         //Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;  
  68.         con.Close();  
  69.   
  70.     }  

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.         //binding chart control  
  55.         Chart1.Series[0].Points.DataBindXY(XPointMember, YPointMember);  
  56.   
  57.         //Setting width of line  
  58.         Chart1.Series[0].BorderWidth = 4;  
  59.         //setting Chart type   
  60.         Chart1.Series[0].ChartType = SeriesChartType.RangeBar;  
  61.        
  62.         //Hide or show chart back GridLines  
  63.         // Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;  
  64.         //Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;  
  65.   
  66.         //Enabled 3D  
  67.         //Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;  
  68.         con.Close();  
  69.   
  70.     }  

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.
