Constructor Detail

ArrayXYSeries

public ArrayXYSeries()

Construct a new uninitialized array X-Y series. This constructor is for use only by object deserialization.

ArrayXYSeries

public ArrayXYSeries(double[] xarray,
                     double[] yarray)

Construct a new array X-Y series.

Parameters:

xarray - Array of X values.

yarray - Array of Y values.

Throws:

java.lang.NullPointerException - (unchecked exception) Thrown if xarray is null or yarray is null.

java.lang.IllegalArgumentException - (unchecked exception) Thrown if xarray and yarray are not the same length.

Method Detail

length

public int length()

Returns the number of values in this series.

Specified by:

length in class XYSeries

Returns:

Length.

x

public double x(int i)

Returns the given X value in this series.

Specified by:

x in class XYSeries

Parameters:

i - Index.

Returns:

The X value in this series at index i.

Throws:

java.lang.ArrayIndexOutOfBoundsException - (unchecked exception) Thrown if i is not in the range 0 .. length()-1.

y

public double y(int i)

Returns the given Y value in this series.

Specified by:

y in class XYSeries

Parameters:

i - Index.

Returns:

The Y value in this series at index i.

Throws:

java.lang.ArrayIndexOutOfBoundsException - (unchecked exception) Thrown if i is not in the range 0 .. length()-1.

xSeries

public Series xSeries()

Returns a Series view of the X values in this XY series.

Note: The returned Series object is backed by this XY series object. Changing the contents of this XY series object will change the contents of the returned Series object.

Overrides:

xSeries in class XYSeries

Returns:

Series of X values.

ySeries

public Series ySeries()

Returns a Series view of the Y values in this XY series.

Note: The returned Series object is backed by this XY series object. Changing the contents of this XY series object will change the contents of the returned Series object.

Overrides:

ySeries in class XYSeries

Returns:

Series of Y values.

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Write this X-Y series to the given object output stream.

Specified by:

writeExternal in interface java.io.Externalizable

Parameters:

out - Object output stream.

Throws:

java.io.IOException - Thrown if an I/O error occurred.

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException

Read this X-Y series from the given object input stream.

Specified by:

readExternal in interface java.io.Externalizable

Parameters:

in - Object input stream.

Throws:

java.io.IOException - Thrown if an I/O error occurred.
