data model

The scheduling information you want to represent as a chart. One major feature of Rogue Wave JViews Gantt is that the data model is separated from the visualization part.

data node

A node in a hierarchical structure that represents an activity in a Gantt chart or a resource in a Schedule chart.

declaration

(CSS.) The right side of a style rule. A declaration is enclosed within braces ({}). It consists of at least one property-value pair. Each property-value pair ends with a semi-colon (;). A property value pair sets a rendering property on a graphic object that represents a model object.

demurrage

A charge for detaining a ship beyond the time allowed for loading, unloading, or sailing.

displayed data node

A data node that is visible (its parent is expanded) and currently within the display area where it can be seen. See also user-defined type. (Scrolling changes display status, not visibility status.)

duration

The interval between the start time and the end time of an activity. The duration of an activity may be null or zero, in which case the activity is a milestone.
