In the 2006 Volume 3 release, we’ve improved the WinChart™ control to make it easy for you to hide or display a series in a Composite or non-composite chart. Previously, to show or hide a series, you needed to add/remove the series from the Series collection. In 2006 Volume 3, we’ve added a new Visible property to the Series object.
This convenient feature is a time-saver, as it allows you to specify whether you want to hide or display the series by the simple setting of a property, rather than having to add/remove the series from the Series collection.
