Organizar gráfico c#

Recommended Posts


Pessoal estou fazendo um gráfico apartir de um banco de dados com datas eu queria organizar a data para mostrar no gráfico em ordem crescente

olha o codigo

               MySqlConnection connection = new MySqlConnection("server = localhost;userid=root;database=tbfaz;password=123");
               MySqlCommand mycommand = connection.CreateCommand();
               mycommand.CommandText = "SELECT * FROM tbgrafico WHERE usuario LIKE '%" + temporario + "%'";
               MySqlDataAdapter myDA = new MySqlDataAdapter(mycommand);

               MySqlDataReader reader = mycommand.ExecuteReader();

               while (reader.Read())
                   String local = reader["fazenda"].ToString() +" : "+ reader["data"].ToString();
                   chart1.Series[0].ChartType = SeriesChartType.Line;
                   chart1.Series[0].Points.AddXY(local, reader["bezerro"].ToString());
                   chart1.Series[0].IsValueShownAsLabel = true;

eu teria que organizar o banco de dados ou o chart1 organiza para mim?
