Chart creating dynamically in net c

Question

Does anybody have some experience working with charts in  NET  Specially I want to create them programmatically   using System  using System Collections Generic  using System ComponentModel  using System Data  using System Drawing  using System Linq  using System Text  using System Windows Forms  using System Windows Forms DataVisualization Charting  using System Diagnostics   namespace WindowsFormsApplication6     public partial class Form1   Form         public Form1                 InitializeComponent               private void Form1 Load object sender  EventArgs e                Random rnd   new Random            Chart mych   new Chart            mych Series Add  duck             mych Series  duck   SetDefault true           mych Series  duck   Enabled   true          mych Visible   true           for  int q   0  q  lt  10  q                          int first   rnd Next 0 10               int second   rnd Next 0 10               mych Series  duck   Points AddXY first  second               Debug WriteLine first          second                     mych Show            Controls Add mych           mych Show                  I m trying to use  NET   net 4  Visual Studio 2010  chart  but the random generated data set  doesn t appear  The chart remained blank  I searched for examples and only found ones like   this   and  yes with manual  drag  method it works  I have no idea why the data I programmatically generate doesn t appear

Add a reference to System Windows Form DataVisualization  then add the appropriate using statement   using System Windows Forms DataVisualization Charting   private void CreateChart         var series   new Series  Finance            Frist parameter is X-Axis and Second is Collection of Y- Axis     series Points DataBindXY new     2001  2002  2003  2004    new     100  200  90  150         chart1 Series Add series

You need to attach the Form1 Load handler to the Load event   using System  using System Collections Generic  using System ComponentModel  using System Data  using System Drawing  using System Linq  using System Text  using System Windows Forms  using System Windows Forms DataVisualization Charting  using System Diagnostics   namespace WindowsFormsApplication6       public partial class Form1   Form               public Form1                         InitializeComponent                Load    Form1 Load                     private void Form1 Load object sender  EventArgs e                        Random rnd   new Random                Chart mych   new Chart                mych Height   100              mych Width   100              mych BackColor   SystemColors Highlight              mych Series Add  duck                 mych Series  duck   SetDefault true               mych Series  duck   Enabled   true              mych Visible   true               for  int q   0  q  lt  10  q                                  int first   rnd Next 0  10                   int second   rnd Next 0  10                   mych Series  duck   Points AddXY first  second                   Debug WriteLine first          second                              Controls Add mych
