The IlvHierarchyChart class is the base class for IlvGanttChart and IlvScheduleChart. The left part of the chart is an IlvJTable that displays the activities or resources of a given IlvGanttModel as a tree structure. The right part of the chart is an IlvGanttSheet showing activities or reservations.

The Hierarchy chart supports alternate locales by utilizing resource files. The resource files are documented here.

Two horizontal time scrolling modes are supported by the chart:

Bounded scrolling mode: In this mode, time scrolling is constrained by the minimum visible time and the maximum visible time. Both values must be valid and non-null.
In bounded scrolling mode there are four interrelated time properties: minVisibleTime, maxVisibleTime, visibleTime, and visibleDuration. These four values define two nested ranges like this:
```
  minVisibleTime <= visibleTime <= visibleTime+visibleDuration <= maxVisibleTime
```
The chart enforces this relationship by correcting or trimming properties according to the following rules:
- The setMinVisibleTime(java.util.Date) and setMaxVisibleTime(java.util.Date) methods first validate that:
```
  minVisibleTime <= maxVisibleTime 
```
  If not, an IllegalArgumentException is thrown. Next, the visible time and visible duration properties may be trimmed (in that order), to fit within the new min-max interval.
- The setVisibleTime(java.util.Date) and extent setVisibleDuration(ilog.views.gantt.IlvDuration) methods trim their argument to fit within the limits defined by the other three properties. For example if maxVisibleTime.equals(visibleTime.add(IlvDuration.ONE_DAY)), then setVisibleDuration(IlvDuration.ONE_WEEK) would change the duration to IlvDuration.ONE_DAY.
The chart uses the IlvTimeScrollUtil.trimInterval(IlvTimeScrollable, IlvTimeInterval) method to perform consistent validation and trimming of the time value arguments.
Unbounded scrolling mode: In this mode, the minimum visible time and the maximum visible time are undefined and are set to null.
Even in unbounded scrolling mode, there is an inherent limitation on the minimum and maximum times that can be scrolled to. As in bounded scrolling mode, this is enforced by having the chart use the IlvTimeScrollUtil.trimInterval(IlvTimeScrollable, IlvTimeInterval) method to perform validation and trimming of the time value arguments.

The following default keyboard actions are installed on the chart and its sub-components by default:

Action	KeyStroke	Component	Condition
`Zoom In`	`Control-Z`	Chart	`WHEN_ANCESTOR_OF_FOCUSED_COMPONENT`
`Zoom Out`	`Control-U`	Chart	`WHEN_ANCESTOR_OF_FOCUSED_COMPONENT`
`Scroll Up`	`Up Arrow`	Right Gantt Panel	`WHEN_ANCESTOR_OF_FOCUSED_COMPONENT`
`Scroll Down`	`Down Arrow`	Right Gantt Panel	`WHEN_ANCESTOR_OF_FOCUSED_COMPONENT`
`Scroll Time Left`	`Left Arrow`	Right Gantt Panel	`WHEN_ANCESTOR_OF_FOCUSED_COMPONENT`
`Scroll Time Right`	`Right Arrow`	Right Gantt Panel	`WHEN_ANCESTOR_OF_FOCUSED_COMPONENT`
