Legend Series Name

[Joel]

How do I change the name of the series programmatically for display in the legend?  (Chart Object)

I have this as my needdatasource event and every time I try to hit series(0) I get index out of range errors.   I have a datatable that always returns 3 columns of label, x, y and need to name x and y to what the user selects.  (x = sales, y =volume).  I have seen a number of examples, and tried them, but to no avail.

    Private Sub Chart1_NeedDataSource(ByVal sender As Object, ByVal e As EventArgs) Handles Chart1.NeedDataSource
        Dim chart As Telerik.Reporting.Processing.Chart = TryCast(sender, Telerik.Reporting.Processing.Chart)
        Dim mydt As DataTable
        mydt = GetDTNoQ()
        Dim mycount As Int32 = CInt(mydt.Rows.Count / 8)
        Chart1.PlotArea.XAxis.LabelStep = mycount
        chart.DataSource = mydt
        'Dim mySeries As Telerik.Reporting.Charting.ChartSeries = Chart1.Series.GetSeries(0)
        'mySeries.Name = "Sales"
    End Sub
