        Dim linea As Infragistics.UltraChart.Core.Primitives.Line

        Try
            Dim x As Infragistics.UltraChart.Core.IAdvanceAxis = e.Grid("X")
            Dim y As Infragistics.UltraChart.Core.IAdvanceAxis = e.Grid("Y")

            media = UltraGrid1.DisplayLayout.Rows.SummaryValues("m" & UltraGrid1.DisplayLayout.Bands(0).Columns(UltraComboTestate.Value).Key).Value
            linea = New Infragistics.UltraChart.Core.Primitives.Line(New Point(x.Map(0), y.Map(media)), New Point(x.Map(50), y.Map(media)))
