How to prevent chart clustering using DataBindCrossTable in c#?

try

                ArrayList listofdates = dbmanager.GetListofDatesViaAll(); 
 
                foreach (DateTime date in listofdates)

                    double gradingresult = dbmanager.GetAverageAppraisalForSectionALL(date); 
 
                    string monthname = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(date.Month); 
                    table.Rows.Add(gradingresult, monthname.Substring(0, 3) + "/" + date.Year.ToString().Substring(2, 2)); 
                } 
                DataTableReader datareader = table.CreateDataReader();
