Hi Tom,
Thanks for your interest in Syncfusion products.
We could use the Legend ItemTemplate and show the X, Y or the label values in the legend items.
Please refer to the sample from the below given link that has a DataTemplate written for legend items
http://files.syncfusion.com/support/Chart.WPF/7.3.0.20/F88123/main.htmIn the DataTemplate DataPoint.Item is used to show the labels. Here you could also use DataPoint.X, or Y.
This DataTemplate is assigned to the legend in VB file as shown below.
objLegend.ItemTemplate = TryCast(Me.Resources("LegendTemplate"), DataTemplate)
Please let us know if you have further queries.
Regards,
K. Saradha Devi
