Examples of org.jfree.data.time.TimeSeriesDataItem

org.jfree.data.time.TimeSeriesDataItem
Represents one data item in a time series.
The time period can be any of the following:
- {@link Year}
- {@link Quarter}
- {@link Month}
- {@link Week}
- {@link Day}
- {@link Hour}
- {@link Minute}
- {@link Second}
- {@link Millisecond}
- {@link FixedMillisecond}
The time period is an immutable property of the data item. Data items will often be sorted within a list, and allowing the time period to be changed could destroy the sort order.
Implements the Comparable interface so that standard Java sorting can be used to keep the data items in order.
