All Implemented Interfaces:

IPolicy, IGridLinePolicy

public class TimeGranularityGridLinePolicy
extends DefaultGridLinePolicy

A specialization of the default grid line policy for situations where the TimeGranularityDatelineModel gets used by the dateline. This policy takes into account that depending on the major and the minor time granularities the major and minor grid lines will not be on top of each other causing a messy grid line appearance. In these cases the policy will turn off the major grid lines. For a more general description of this policy please refer to the policy interface IDragAndDropPolicy.
