public class DateTitle
extends TextTitle
implements Serializable

A chart title that displays the date.

Keep in mind that a chart can have several titles, and that they can appear at the top, left, right or bottom of the chart - a DateTitle will commonly appear at the bottom of a chart, although you can place it anywhere.

By specifying the locale, dates are formatted to the correct standard for the given locale. For example, a date would appear as "January 17, 2000" in the US, but "17 January 2000" in most European locales.
