DataLabel Property

Returns a DataLabel object that represents the data label associated with the specified point or trendline. Read-only.

This example turns on the data label for point seven in series three, and then it sets the data label color to blue.

With myChart.SeriesCollection(3).Points(7) 
 .HasDataLabel = True 
 .ApplyDataLabels type:=xlValue 
 .DataLabel.Font.ColorIndex = 5 
End With
