Examples of TimeSeries

ca.nengo.util.TimeSeries
A series of vector values at ordered points in time. @author Bryan Tripp
com.opengamma.timeseries.TimeSeries
A time-series, which represents the changes in a value over time.
This interface is similar to both a {@code SortedMap} of value keyed by date-timeand a {@code List} of date-time to value pairs.As such, the date/times do not have to be evenly spread over time within the series. @param < T> the date-time type, such as {@code Instant} or {@code LocalDate} @param < V> the value being viewed over time, such as {@code Double}
com.timeseries.TimeSeries
org.apache.jackrabbit.api.stats.TimeSeries
Interface for a time series of the measured values per second, minute, hour and day. The type of the value is arbitrary; it could be cache hits or misses, disk reads or writes, created sessions, completed transactions, or pretty much anything of interest. @since Apache Jackrabbit 2.3.2
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.
