public class 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.
| 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. |
|
TimeSeriesCollection(java.util.TimeZone zone)
Constructs an empty dataset, tied to a specific timezone. |

java.lang.Comparable |
getSeriesKey(int series)
Returns the key for a series. |
java.lang.Number |
getStartX(int series,
int item)
Returns the starting X value for the specified series and item. |
java.lang.Number |

int item)
Returns the starting Y value for the specified series and item. |
int[] |
getSurroundingItems(int series,
long milliseconds)
Returns the indices of the two data items surrounding a particular millisecond value. |
java.lang.Number |
getX(int series,
int item)
Returns the x-value for the specified series and item. |
protected long |
getX(RegularTimePeriod period)
Returns the x-value for a time period. |
TimePeriodAnchor |
getXPosition()
Returns the position within each time period that is used for the X value when the collection is used as an XYDataset. |
double |
getXValue(int series,
int item)
Returns the x-value (as a double primitive) for an item within a series. |
java.lang.Number |
getY(int series,
int item)
Returns the y-value for the specified series and item. |
int |
hashCode()
Returns a hash code value for the object. |
int |
indexOf(TimeSeries series)
Returns the index of the specified series, or -1 if that series is not present in the dataset. |
void |
removeAllSeries()
Removes all the series from the collection and sends a DatasetChangeEvent to all registered listeners. |
void |
removeSeries(int index)
Removes a series from the collection. |
void |
removeSeries(TimeSeries series)
Removes the specified series from the collection and sends a DatasetChangeEvent to all registered listeners. |
void |
setDomainIsPointsInTime(boolean flag)
Deprecated. This flag is no longer used, as of 1.0.1. The includeInterval flag in methods such as
getDomainBounds(boolean) makes this unnecessary. |
void |
setXPosition(TimePeriodAnchor anchor)
Sets the position within each time period that is used for the X values when the collection is used as an XYDataset, then sends a
DatasetChangeEvent is sent to all registered listeners. |
