   {

       GraphPane myPane = masterPane[0];
       string[] labels = { "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" };
       double[] x4 = { 80, 50, 20, 20, 90, 80, 30, 50, 60, 30, 80, 70 };
       myPane.Fill = new Fill(Color.White, Color.Goldenrod, 45.0f);
       myPane.Chart.Fill.Type = FillType.None;
       myPane.Legend.Position = LegendPos.Float;
       myPane.Legend.Location = new Location(0.95f, 0.15f, CoordType.PaneFraction, AlignH.Right, AlignV.Top);
       myPane.Legend.FontSpec.Size = 10f;
