Class VectorSeries
- Cloneable, Serializable
A list of (x,y, deltaX, deltaY) data items.
VectorSeries(Comparable key) - Creates a new empty series.
|
VectorSeries(Comparable key, boolean autoSort, boolean allowDuplicateXValues) - Constructs a new series that contains no data.
|
void | add(double x, double y, double deltaX, double deltaY) - Adds a data item to the series.
|
ComparableObjectItem | getDataItem(int index) - Returns the data item at the specified index.
|
double | getVectorXValue(int index) - Returns the x-component of the vector for an item in the series.
|
double | getVectorYValue(int index) - Returns the y-component of the vector for an item in the series.
|
double | getXValue(int index) - Returns the x-value for the specified item.
|
double | getYValue(int index) - Returns the y-value for the specified item.
|
ComparableObjectItem | remove(int index) - Removes the item at the specified index and sends a
SeriesChangeEvent to all registered listeners.

VectorSeries
public VectorSeries(Comparable key)
Creates a new empty series.
key
- the series key (null
not permitted).
VectorSeries
public VectorSeries(Comparable key,
boolean autoSort,
boolean allowDuplicateXValues)
Constructs a new series that contains no data. You can specify
whether or not duplicate x-values are allowed for the series.
key
- the series key (null
not permitted).autoSort
- a flag that controls whether or not the items in the
series are sorted.allowDuplicateXValues
- a flag that controls whether duplicate
x-values are allowed.
add
public void add(double x,
double y,
double deltaX,
double deltaY)
Adds a data item to the series.
x
- the x-value.y
- the y-value.deltaX
- the vector x.deltaY
- the vector y.
getVectorXValue
public double getVectorXValue(int index)
Returns the x-component of the vector for an item in the series.
- The x-component of the vector.
getVectorYValue
public double getVectorYValue(int index)
Returns the y-component of the vector for an item in the series.
- The y-component of the vector.
getXValue
public double getXValue(int index)
Returns the x-value for the specified item.
getYValue
public double getYValue(int index)
Returns the y-value for the specified item.
