IlvTimeScaleVisibilityPolicy
```
public class IlvGanttTimeScaleVisibilityPolicy
extends IlvBasicTimeScaleVisibilityPolicy
```
Implements a visibility policy for the IlvGanttTimeScale. This policy enforces two of the predefined rows to be visible at a time, depending on the zoom level of the time scale.
This policy defines 16 visibility conditions depending upon the zoom level that are processed in the following order:
- The MINUTE_VISIBILITY condition, when the zoom level enables to display at the minute level.
- The FIVE_MINUTE_VISIBILITY condition, when the zoom level enables to display every five minutes.
- The FIFTEEN_MINUTE_VISIBILITY condition, when the zoom level enables to display every fifteen minutes.
- The HOUR_VISIBILITY condition, when the zoom level enables to display every hour.
- The FOUR_HOUR_VISIBILITY condition, when the zoom level enables to display every four hours.
- The DAY_VISIBILITY condition, when the zoom level enables to display every day using a medium format.
- The SHORT_DAY_VISIBILITY condition, when the zoom level enables to display every day using a short format.
- The WEEK_VISIBILITY condition, when the zoom level enables to display every week.
- The MONTH_VISIBILITY condition, when the zoom level enables to display every month.
- The MEDIUM_MONTH_VISIBILITY condition, when the zoom level enables to display every month using a medium format.
- The SHORT_MONTH_VISIBILITY condition, when the zoom level enables to display every month using a short format.
- The QUARTER_VISIBILITY condition, when the zoom level enables to display every quarter.
- The YEAR_VISIBILITY condition, when the zoom level enables to display every year.
- The FIVE_YEAR_VISIBILITY condition, when the zoom level enables to display every five years.
- The TEN_YEAR_VISIBILITY condition, when the zoom level enables to display every ten years.
- The FIFTY_YEAR_VISIBILITY condition, when the zoom level enables to display every fifty years.
- The HUNDRED_YEAR_VISIBILITY condition, when the zoom level enables to display every hundred years.
