VS 2008 - How To Make DataSet As A Source For Microsoft Chat Control

I have a simple .aspx page. I am using VS 2008. I have a microsoft chart control on the page. In the page_load event, I would like to to populate the chart control. I wrote the following code. I can see the data in the dataset. But for some reason, the data is not seen in the chart control.

Code:
protected void Page_Load(object sender, EventArgs e)
{
DataSet adataset;
string Sql = "select count " + '|'+'|' + "unit as Tenor, value from qrm.advancecurve order by days asc";
Database db = DatabaseFactory.CreateDatabase("ConnectionString_OracleQRM");
