DateTimeCategoryAxis class
An axis which is used to plot date-time values. It is similar to DateTimeAxis except that it excludes missing dates.
This is a unique type of axis used mainly with financial series. Like CategoryAxis, all the data points are plotted with equal spaces by removing space for missing dates. Intervals and ranges for the axis are calculated similar to DateTimeAxis. There will be no visual gaps between points even when the difference between two points is more than a year.
A simple use case of this axis type is when the user wishes to visualize the working hours on an employee for a month by excluding the weekends.
Provides options for label placement, interval, date format for customizing the appearance.
