DESCRIPTION
The Data Visualization components in ADF allow for turning data into information using a large variety of representations. The DVT library ranges from bar, pie and line chart to map, gantt and gauge. With others in between. On our ADF Special Interest Group at AMIS, we discussed six components from the DVT collection. This presentation is one out of those six - on Gantt Charts.

DATA MODEL FOR PROJECT GANTT-CHART
FANCY DATA MODEL ASPECTS
• Detail accessors are supported in the Project Gantt:– SubTasks– Dependent Tasks– Split Tasks– Recurring Tasks
DATA MODEL FOR SCHEDULING GANTT• ADF TreeTable Model or CollectionModel
representing Resources• Per Resource:
– a unique Resource Id – also a tasks accessor for
the collection of ‘scheduled periods’ for the resource
• Each Task (or Allocation)element has an Id, a Start Time and an End Time– Optionally a type

SUPPORTING DRAG & DROP
• Define dataChangeListener on Gantt Chart• Decipher Data Change event
– Extract Source Resource, Target Resource & Drop Time
• Update model– Remove ‘task’ from allocations under Source
Resource– Add ‘task’ to allocations under Target Resource
• Refresh Iterator• Refresh Gantt Chart (as partial target)
DATA MODEL FOR RESOURCE UTILIZATION GANTT• ADF TreeTable Model or CollectionModel
representing Resources• Per Resource:
– a unique Resource Id attribute– Also a time buckets
accessor for the collection of ‘period records’ for the resource
• Each Time Bucket element has – a Date to indicate the when
of the bucket– any metrics (numerical) that
