Gantt charts allow to display the chronology of tasks and to plan the capacity of resources.
Due to their graphical visualization, interrelations and deviations become obvious at a glance.

Working with the Gantt Bean is made as simple as possible within Servoy. On the other hand this does not mean that you are limited at all:

• Work with FoundSets to autoSave all your changes
• Work with DataSets when your data is more static or when you want more control
• Capture all events before they occur to prevent changes
• Create, Update and Delete tasks from the Bean
• Display tasks (and links) in hierarchical mode
• Display tasks (and links) in group mode
• Group tasks with or without (collapsable) summury row

Part of the Gantt Bean in action in Hierarchy View, showing part of the Table and including Links.


Part of the Gantt Bean in action in Grouping View, showing alternated colors per Group in 3d effect.


Part of the Gantt Bean in action in Folded Grouping View, showing alternated colors and Summary rows.

Our Gantt Bean is based on the Varchart JGantt libraries by Netronic.
Netronic has put more than 3 decades of work into their Gantt libraries.

• Your client asks for advanced Project management tools.
• Your client needs Resource management.

Every Solution that needs to display and/or manage tasks and/or resources will benefit.
