PointAndFigure Chart Type In ASP.Net

Background

Today we will discuss the PointAndFigure type chart of ASP.Net. We will learn about this chart type control step-by-step. Now let us learn about the properties of the PointAndFigure charts. A PointAndFigure chart type has the following common properties:
  • 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 for 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 a table for the chart data:
  1. CREATE TABLE [dbo].[orderdet](  
  2.     [id] [int] IDENTITY(1,1) NOT NULL,  
  3.     [Month] [varchar](50) NULL,  
  4.     [Orders] [int] NULL,  
  5.  CONSTRAINT [PK_Order Table] PRIMARY KEY CLUSTERED   
  6. (  
  7.     [id] ASC  
  8. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]  
  9. ) ON [PRIMARY]  
  10.   
  11. GO 
Now the design will look as follows:
 
 
Now insert the records using the following script:
  1. SET IDENTITY_INSERT [dbo].[orderdet] ON           
  2.           
  3. GO          
  4. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (1, N'Jan', 0)          
  5. GO          
  6. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (2, N'Feb', 5)          
  7. GO          
  8. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (3, N'March', 20)          
  9. GO          
  10. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (4, N'April', 40)          
  11. GO          
  12. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (5, N'May', 15)          
  13. GO          
  14. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (6, N'Jun', 60)          
  15. GO          
  16. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (7, N'July', 75)          
  17. GO          
  18. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (8, N'Aug', 80)          
  19. GO          
  20. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (9, N'Sep', 85)          
  21. GO          
  22. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (10, N'Oct', 100)          
  23. GO          
  24. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (11, N'Nov', 2)          
  25. GO          
  26. INSERT [dbo].[orderdet] ([id], [Month], [Orders]) VALUES (12, N'Dec', 90)          
  27. GO          
  28. SET IDENTITY_INSERT [dbo].[orderdet] OFF          
  29. 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 "PointAndFigure" 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="black">  
  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="192, 64, 0" BackGradientStyle="LeftRight"  
  16.         BorderlineWidth="0" Height="360px" Palette="None" PaletteCustomColors="128, 64, 0"  
  17.         Width="380px" BorderlineColor="255, 128, 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. Then 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.         }  
  24.         //binding chart control  
  25.         Chart1.Series[0].Points.DataBindXY(XPointMember, YPointMember);  
  26.   
  27.         //Setting width of line  
  28.         Chart1.Series[0].BorderWidth = 1;  
  29.         //setting Chart type   
  30.          Chart1.Series[0].ChartType = SeriesChartType.PointAndFigure;  
  31.        
  32.         //Hide or show chart back GridLines  
  33.   // Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;  
  34.   // Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;  
  35.   
  36.         //Enabled 3D  
  37.       // Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;  
  38.         con.Close();  
  39.   
  40.     } 
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.   
  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 = 1;  
  63.         //setting Chart type   
  64.          Chart1.Series[0].ChartType = SeriesChartType.PointAndFigure;  
  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.     }  
  75. } 
 Now, we have the entire logic to bind the chart from the database, let us run the application. The PointAndFigureChart will then look as follows:
 
 
 
 Now change the Border width and color as:
  1. //Setting width of line      
  2.  Chart1.Series[0].BorderWidth = 4;     
 Now PointAndFigure 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 PointAndFigure chart will be as follows:
 
 
 
The preceding is the Normal PointAndFigure 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 chart will be as:
 
 
 
Now let us limit the Border width as compared to the preceding:
  1. //Setting width of line      
  2.  Chart1.Series[0].BorderWidth = 2;     
Now the PointAndFigure chart will look as follows:
 
 
 
Let us hide the Grid Line in 3D style 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 PointAndFigure will look as follows:
 
 
 
Now from all the preceding explanations we saw how to create and use a PointAndFigure type 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.
