Whenever data exists in the chart, a Legend is automatically generated. The chart assigns the name specified in the ChartDataSeries object for the series as the series identifier. LineStyle and SymbolStyle determine the symbols that accompany the series name in the Legend. The positioning, border, colors and font used for the Legend can be customized.

To programmatically modify the Legend properties:

Sample property settings are listed below:

To write code in Visual Basic

C1Chart3D1.Legend.Compass = CompassEnum.East
C1Chart3D1.Legend.Style.Border.BorderStyle = BorderStyleEnum.Solid
C1Chart3D1.Legend.Style.Border.Thickness = 3
C1Chart3D1.Legend.Style.Border.Color = Color.Black
C1Chart3D1.Legend.Style.BackColor = Color.Gray
C1Chart3D1.Legend.Text = "Legend Text"

To write code in C#

 c1Chart3D1.Legend.Compass = CompassEnum.East;
 c1Chart3D1.Legend.Style.Border.BorderStyle = BorderStyleEnum.Solid;
 c1Chart3D1.Legend.Style.Border.Thickness = 3;
 c1Chart3D1.Legend.Style.Border.Color = Color.Black;
 c1Chart3D1.Legend.Style.BackColor = Color.Gray;
 c1Chart3D1.Legend.Text = "Legend Text";

The code above would look as follows using this method:

To write code in Visual Basic

With C1Chart3D1.Legend
   .Compass = CompassEnum.East
   With .Style
       With.Border
          .BorderStyle = BorderStyleEnum.Solid
          .Thickness = 3
          .Color = Color.Black
       End With
       .BackColor = Color.Gray
   End With
.Text = "Legend Text"
End With

To write code in C#

    
C1.Win.C1Chart3D.Legend legend = C1Chart3D1.Legend;
C1.Win.C1Chart3D.Style style = legend.Style;
C1.Win.C1Chart3D.Border border = style.Border;

legend.Compass = CompassEnum.East;
border.BorderStyle = BorderStyleEnum.Solid;
border.Thickness = 3;
border.Color = Color.Black;
style.BackColor = Color.Grey;
legend.Text = "Legend Text";
