The following members accept/return Legend objects:


The Legend class contains the settings that define the legend functionality within a chart control. An object of the Legend type can be accessed using a chart control's ChartControl.Legend and ChartControl.Legendsproperties.

The legend identifies different chart elements (such as series, constant lines and strips). An element is represented in the legend when its ShowInLegend property is enabled (in particular, the SeriesBase.ShowInLegend, ConstantLine.ShowInLegend and Strip.ShowInLegend properties).

The properties provided by the Legend class allow you to control the following legend options.

For more information, refer to Legends.


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.
