public class BoxTimeScaleRenderer
Timescalerenderer rendering strips of boxes for different time intervals using DateIterator instances. A holiday enumerator can be used to display special and holidays in the tooltip. Supports horizontal and vertical operation (vertical might be imperformant since vertical text is used).
