Method Detail

addChangeListener

public void addChangeListener(org.jfree.data.DatasetChangeListener zListener)

Registers an object for notification of changes to the dataset.

Specified by:

addChangeListener in interface org.jfree.data.Dataset

Parameters:

zListener - the listener

removeChangeListener

public void removeChangeListener(org.jfree.data.DatasetChangeListener zListener)

Deregisters an object for notification of changes to the dataset.

Specified by:

removeChangeListener in interface org.jfree.data.Dataset

Parameters:

zListener - the listener

set

public void set(ArrayList<Number> zXData,
                ArrayList<Number>[] zYData,
                String[] zYSeriesName)
         throws Exception

to set the values of the model

Parameters:

zXData - the number of X values

zYData - a list of Y values arrays (one array for each serie i.e. one array for each Y line to draw)

zYSeriesName - the name of the Y series

Throws:

Exception - if an error occurs

getItemCount

public int getItemCount(int zSeries)

Returns the number of X items in the specified series. In this inplementation, all series (i.e. all Y curves to draw) have the same number of items

Specified by:

getItemCount in interface org.jfree.data.XYDataset

Parameters:

zSeries - The index (zero-based) of the series;

Returns:

The number of items in the specified series.

getSeriesCount

public int getSeriesCount()

Returns the number of series in the data set (i.e. number of Y lines to draw)

Specified by:

getSeriesCount in interface org.jfree.data.SeriesDataset

Returns:

The number of series in the data source.

getSeriesName

public String getSeriesName(int zSeries)

Returns the name of the series (i.e. Y curve to draw).

Specified by:

getSeriesName in interface org.jfree.data.SeriesDataset

Parameters:

zSeries - The index (zero-based) of the series;

Returns:

The name of the series.

getXValue

public Number getXValue(int zSeries,
                        int zItem)

Returns the x-value for the specified series (i.e. Y curve to draw) and item. Series are numbered 0, 1, ... The implementation is responsible for ensuring that the x-values are presented in ascending order

Specified by:

getXValue in interface org.jfree.data.XYDataset

Parameters:

zSeries - The index (zero-based) of the serie (i.e. Y curve to draw);

zItem - The index (zero-based) of the required item;

Returns:

The x-value for the specified series and item.

getYValue

public Number getYValue(int zSeries,
                        int zItem)

Returns the y-value for the specified series and item. Series are numbered 0, 1, ...

Specified by:

getYValue in interface org.jfree.data.XYDataset

Parameters:

zSeries - The index (zero-based) of the series;

zItem - The index (zero-based) of the required item;

Returns:

The y-value for the specified series and item.

setGroup

public void setGroup(org.jfree.data.DatasetGroup zGroup)

Sets the dataset group.

Specified by:

setGroup in interface org.jfree.data.Dataset

Parameters:

zGroup - the dataset group.

getGroup

public org.jfree.data.DatasetGroup getGroup()

get the dataset group.

Specified by:

getGroup in interface org.jfree.data.Dataset

Returns:

the dataset group.
