title: Chart binding with database problem cause Date format
body: <p>I'm trying to bind chart to database. Database contains more columns (id,sum , date , categoryID, and many more. My problem is, im not able to bind chart with sum and date. Sum should be on Y axes and date should be on X axes. I beginner in C# so probably im doing something wrong there. Every time when I click button there is a chart but with wrong values.</p>
  
  <pre><code>string commandString = "select sum, date from wallettbl order by date";
  cmd = new SqlCommand(commandString, con); 
  con.Open();
  SqlDataReader dataReader;
  dataReader = cmd.ExecuteReader();  
  
          while (dataReader.Read())
          {             
           this.chart1.Series["Series1"].Points.AddXY(dataReader["sum"], dataReader["date"]); 
           this.chart1.ChartAreas["ChartArea1"].AxisX.LabelStyle.Format = "dd/mm/yyyy";
         }
  
          con.Close();
  </code></pre>
  
  <p>I expected to have chart with my data from database, and every time when I click button it will be realoaded, again not added to the current one.</p>
