How to: Hide an Individual Series Label
This example demonstrates how to hide an individual series label.
Handle the ChartControl.CustomDrawSeriesPoint event to conditionally hide series labels. In the event handler, change the CustomDrawSeriesPointEventArgs.LabelText property value to String.Empty to hide a label.
Note that to perform the same for the Chart Control for ASP.NET, it is necessary to handle the WebChartControl.CustomDrawSeriesPoint event.
