RangeColumn Chart Type in ASP.Net

Background

Today we will discuss the RangeColumn Chart type of ASP.Net. So let us start to learn about this chart type control step-by-step.

The following are the properties of the RangeColumn Chart Type:

  • AlternetText: Sets the alternate text when the image is not available.

  • Annotation: Stores the chart annotations.

  • AntiAliasing: Sets a value that determines whether anti-aliasing is used when text and graphics are drawn.

  • BackGradientStyle: Sets the orientation for the background gradient for the Chart control. Also determines whether a gradient is used, the default is None.
  • Backcolor: Sets the background color for a chart, the default color is White.

  • BackImage: Sets the background image for the chart control.

  • BackHatchStyle: Sets the hatching style for the chart control, the default is None.

  • Height: Sets the height for the chart control.

  • Width: Sets the width for the chart control.

  • Palette: Sets the style with the color for the chart control, the default style is Chocolate.

  • PaletteCustomColors: Sets the custom color for the chart control.

  • Series: Sets the series collection for the chart control.

  • Legends: Sets the series of legends to the chart.
Now let us show the preceding explanation 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] [int] NULL,        
  11.  CONSTRAINT [PK_Order Table] PRIMARY 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 = ON) ON [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 "UsingRangeColumnChart" 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="blue">    
  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="128, 64, 0" BackGradientStyle="LeftRight"    
  16.         BorderlineWidth="0" Height="340px" Palette="None" PaletteCustomColors="64, 0, 64"    
  17.         Width="360px" BorderlineColor="192, 64, 0">    
  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. Now, open the default.aspx.cs page and create the following function named Bindchart to bind the Chart Control as in the following:
  1. private void Bindchart()  
  2. {  
  3.     connection();  
  4.     com = new SqlCommand("GetCharData", con);  
  5.     com.CommandType = CommandType.StoredProcedure;  
  6.     SqlDataAdapter da = new SqlDataAdapter(com);  
  7.     DataSet ds = new DataSet();  
  8.     da.Fill(ds);  
  9.   
  10.     DataTable ChartData = ds.Tables[0];  
  11.   
  12.     //storing total rows count to loop on each Record  
  13.     string[] XPointMember = new string[ChartData.Rows.Count];  
  14.     int[] YPointMember = new int[ChartData.Rows.Count];  
  15.   
  16.     for (int count = 0; count < ChartData.Rows.Count; count++)  
  17.     {  
  18.         //storing Values for X axis  
  19.         XPointMember[count] = ChartData.Rows[count]["Month"].ToString();  
  20.         //storing values for Y Axis  
  21.         YPointMember[count] = Convert.ToInt32(ChartData.Rows[count]["Orders"]);
  22.     }  
  23.     //binding chart control  
  24.     Chart1.Series[0].Points.DataBindXY(XPointMember, YPointMember);  
  25.   
  26.     //Setting width of line  
  27.     Chart1.Series[0].BorderWidth = 10;  
  28.     //setting Chart type   
  29.     Chart1.Series[0].ChartType = SeriesChartType.RangeColumn;  
  30.        
  31.     //Hide or show chart back GridLines  
  32.     // Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;  
  33.     // Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;  
  34.   
  35.     //Enabled 3D  
  36.     //Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;  
  37.     con.Close();  
  38.   
  39. } 
 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.         DataTable ChartData = ds.Tables[0];  
  41.         //storing total rows count to loop on each Record    
  42.         string[] XPointMember = new string[ChartData.Rows.Count];    
  43.         int[] YPointMember = new int[ChartData.Rows.Count];  
  44.         for (int count = 0; count < ChartData.Rows.Count; count++)    
  45.         {    
  46.             //storing Values for X axis    
  47.             XPointMember[count] = ChartData.Rows[count]["Month"].ToString();    
  48.             //storing values for Y Axis    
  49.             YPointMember[count] = Convert.ToInt32(ChartData.Rows[count]["Orders"]);  
  50.         }    
  51.         //binding chart control    
  52.         Chart1.Series[0].Points.DataBindXY(XPointMember, YPointMember);  
  53.         //Setting width of line    
  54.         Chart1.Series[0].BorderWidth = 10;    
  55.         //setting Chart type     
  56.         Chart1.Series[0].ChartType = SeriesChartType.RangeColumn;   
  57.         //Hide or show chart back GridLines    
  58.         // Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;    
  59.         // Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;   
  60.         //Enabled 3D    
  61.         //Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;    
  62.         con.Close();  
  63.     }    
  64. } 
Now, we have the entire logic to bind the chart from the database, let us run the application. The RangeColumn Chart will look as follows:
 
 
Now let us hide the Grid Lines as in the following:
  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 RangeColumn chart will be as follows:
 
 
The preceding is the Normal Point chart. Now let us enable the 3D style as in the following:
  1. //Enabled 3D    
  2.  Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;   
Now the 3D style RangeColumn chart will be as:
 
 
Now change the BackHatchStyle, then the chart will look as follows:
 
 
Now from all the preceding explanations we saw how to create and use a RangeColumn 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.
