Period Axis Label Generator

[iogan18tm]

Simple DateFormat is bound onto the RegularPeriod, not the whole scale is available to if to make a right label for tick. I'll try to introduce a sample code in a day or two.

General uses are - handle different time dimension scales or make complex formatting like hour number in a week.
