org.jfree.data.AbstractSeriesDataset
org.jfree.data.AbstractXYDataset
org.jfree.data.AbstractIntervalXYDataset
org.jfree.data.time.TimeSeriesCollection
A collection of time series objects.
This class implements the XYDataset
interface, as well as the
extended IntervalXYDataset
interface. This makes it a convenient dataset for use with
the XYPlot
class.
Field Summary | |
static int |
END
Useful constant for controlling the x-value returned for a time period. |
static int |
MIDDLE
Useful constant for controlling the x-value returned for a time period. |
static int |
START
Useful constant for controlling the x-value returned for a time period. |
Constructor Summary | |
TimeSeriesCollection()
Constructs an empty dataset, tied to the default timezone. |
|
TimeSeriesCollection(TimeSeries series)
Constructs a dataset containing a single series (more can be added), tied to the default timezone. |
|
TimeSeriesCollection(TimeSeries series,
java.util.TimeZone zone)
Constructs a dataset containing a single series (more can be added), tied to a specific timezone. |
|
