dynamic binding of chart from database in VS2010 in C#

问题

I have to create charts with dynamic datasource, I have a code. It does not show error but the graph is also not visible on runtime.

Here out_table is the name of my table and ADX is one of its column.

code:

OleDbConnection con1 = new OleDbConnection(@"PROVIDER=Microsoft.ACE.OLEDB.12.0;DATA SOURCE=RS.accdb");
String sqlo = "Select ADX from " + out_table + "";
OleDbCommand myCommand = new OleDbCommand(sqlo, con1);
myCommand.Connection.Open();
OleDbDataReader myreader = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
chart1.DataBindTable(myreader, "ADX");
