By default, the XamDataChart™ does not display a Legend for series added in the chart plot area. If you want to show an individual Legend for each series, you need to add a number of Legend objects to the container of XamDataChart control and then bind each Legend to corresponding Series object’s Legend property. In addition, you must set the Title property for each Series object otherwise its corresponding legend item will display a default series title.
You can also specify the location of the Legend in relationship to the XamDataChart control’s plot area. For more information on this, please refer to Docking Legends topic.
The following example code demonstrates how to add individual Legend for each series defined in the XamDataChart control.
