Legend legend = chartControl1.Legend;

// Display the chart control's legend.
legend.Visible = true;

// Define its margins and alignment relative to the diagram.
legend.Margins.All = 8;
legend.AlignmentHorizontal = LegendAlignmentHorizontal.RightOutside;
legend.AlignmentVertical = LegendAlignmentVertical.Top;

// Define the layout of items within the legend.
legend.Direction = LegendDirection.LeftToRight;
legend.EquallySpacedItems = true;
legend.HorizontalIndent = 8;

legend.MarkerVisible = true;
legend.MarkerSize = new Size(20, 20);
legend.Padding.All = 4;

// Define the limits for the legend to occupy the chart's space.
legend.MaxHorizontalPercentage = 50;

legend.FillStyle.FillMode = FillMode.Gradient;
((RectangleGradientFillOptions)legend.FillStyle.Options).Color2 = Color.Bisque;
