      Dim list As New List(Of MyReg)
      list.Add(New MyReg("fabio", 28, 15, Date.Parse("01/01/2016")))
      list.Add(New MyReg("Paula", 32, 3, Date.Parse("19/04/2016")))
      list.Add(New MyReg("Monica", 47, 90, Date.Parse("9/03/2016")))
      WebDataGrid1.DataSource = list

      Dim series As NumericSeries = New NumericSeries()

      series.Data.DataSource = list
      series.Data.LabelColumn = "Nome"
      series.Data.ValueColumn = "Valor"
      series.DataBind()
      UltraChart1.Series.Add(series)

      UltraChart1.Data.DataBind()

   End Sub

End Class
