How can I bind to a DataSet?
DataSet ds = GetDataSet();
DataView view = ds.Tables[0].DefaultView;
SmoothLineChart chart = new SmoothLineChart();
chart.Legend = "Value 1";
chart.DataSource = view;
chart.DataXValueField = "Description";
chart.DataYValueField = "Value1";
chart.DataBind();
ChartControl1.Charts.Add(chart);
ChartControl1.RedrawChart();

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
LoadChartData();
}
}


private void LoadChartData()
{
string constr = @"Server=TestServer; Database=SampleDatabase; uid=sa; pwd=123;";
string query = "SELECT c.CategoryID, c.CategoryName, " +
" Count(p.UnitPrice) AS 'TotalProducts' " +
" FROM Categories c " +
" INNER JOIN Products p ON c.CategoryID = p.CategoryID " +
" GROUP BY c.CategoryID, c.CategoryName";

SqlDataAdapter da = new SqlDataAdapter(query, constr);
DataTable table = new DataTable();
da.Fill(table);

DataView dv = table.DefaultView;

Chart1.Series["Series1"].Points.DataBindXY(dv, "CategoryName", dv, "TotalProducts");
Chart2.Series["Series1"].Points.DataBindXY(dv, "CategoryName", dv, "TotalProducts");
}
