public class Legend :
ChartElement#Related API Members
The following members return Legend objects:
#Remarks
An object of the Legend type is returned via the ChartBase.Legend property.
The legend identifies chart elements by markers coupled with text.
A series (or its data points) is represented in the legend if the Series.ShowInLegend property is enabled. To also be listed in a legend, other elements (e.g., strips) should have their LegendText property defined (e.g. Strip.LegendText).
To control a legend’s alignment within a chart, use the Legend.HorizontalPosition and Legend.VerticalPosition properties.
A legend and its items are customized via the Legend.ItemTemplate and Legend.ReverseItems properties.
#Example
This example demonstrates how to create a simple Cartesian chart with 3 Stacked Bar series, populate them with data and adjust common settings.
