All Implemented Interfaces:

Serializable, Cloneable

public class DateGraphFormat
extends NumberFormat

DateGraphFormat is the subclass of the NumberFormat class. It produces the x-axis markers as a date by using an internal date format. X-axis values are supposed to be the number of seconds since January 1, 1970, 00:00:00 GMT. To use this format for the x-axis call the method setNumberFormatX(NumberFormat df) of the instance of FunctionGraphsJPanel class with the DateGraphFormat instance instead of NumberFormat.
