Examples of org.jfree.data.time.TimeSeries

org.jfree.data.time.TimeSeries
Represents a sequence of zero or more data items in the form (period, value) where 'period' is some instance of a subclass of {@link RegularTimePeriod}. The time series will ensure that (a) all data items have the same type of period (for example, {@link Day}) and (b) that each period appears at most one time in the series.
