Class GanttSeries

java.lang.Object
  com.jrefinery.data.Series
      com.jrefinery.data.GanttSeries

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class GanttSeries
extends Series
implements java.io.Serializable

A very basic representation of a list of tasks and time allocations.

This class is used as a building block for the GanttSeriesCollection class that implements the IntervalCategoryDataset that, in turn, can be used to construct simple Gantt charts.

This class is incomplete. It implements the bare minimum required to get a simple demo running.
