Gantt Chart Library for WPF and .NET 4 contains task hiearchy and resource scheduling controls with data binding support, customizable look and feel, task and dependency drag and drop operations, resource leveling, culture and theme awareness, printing and exporting support, Microsoft Project® XML compatibility, etc. The interactive Gantt Chart and Schedule Chart controls within the product may be used to display all types of data that can be presented on a timeline (i.e. their date and time being incremented along the X-axis in a chart area), and can be used to display tasks, appointments, or other programmed activities for short or long periods of time. It is therefore easy to use these components to build project management, resource planning, activity scheduling, item programming, execution planning, equipment rental, location sharing, assembly-line production, and many other related types of applications.
