How to: Customize the Appearance of a Chart's Legend
- 2 minutes to read
This example demonstrates how a chart’s Legend can be accessed and customized at runtime.
To control whether series, indicators, Constant Lines and Strips should be shown in the legend, use their SeriesBase.ShowInLegend, Indicator.ShowInLegend, ConstantLine.ShowInLegend and Strip.ShowInLegend properties.
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.VerticalIndent = 8;
legend.TextVisible = true;
legend.TextOffset = 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.MaxVerticalPercentage = 50;
// Customize the legend appearance.
legend.BackColor = Color.Beige;
legend.FillStyle.FillMode = FillMode.Gradient;
((RectangleGradientFillOptions)legend.FillStyle.Options).Color2 = Color.Bisque;
legend.Border.Visible = true;
legend.Border.Color = Color.DarkBlue;
legend.Border.Thickness = 2;
legend.Shadow.Visible = true;
legend.Shadow.Color = Color.LightGray;
legend.Shadow.Size = 2;
// Customize the legend text properties.
legend.Antialiasing = false;
legend.Font = new Font("Arial", 9, FontStyle.Bold);
legend.TextColor = Color.DarkBlue;
