C1Chart includes an AlarmZone Collection Editor that can be accessed through C1Chart's properties at design-time. The AlarmZone Collection Editor consists of a windows form which conveniently allows the users to edit/create AlarmZones. Using the editor, the user can add/remove one or many multiple alarm zones, and modify or set the properties for each alarm zone. For more information on the AlarmZone Collection Editor, see AlarmZone Collection Editor.
