Method Detail

init

protected void init()

getAnnotationCount

public abstract int getAnnotationCount()

Description copied from interface: AnnotationModel

Returns the number of annotations

Specified by:

getAnnotationCount in interface AnnotationModel

Returns:

the number of annotations

getAnnotation

public abstract Annotation getAnnotation(int n)

Description copied from interface: AnnotationModel

Gets the nth annotation.

Specified by:

getAnnotation in interface AnnotationModel

Parameters:

n - the index.

Returns:

the nth annotation

getPoint

public abstract Chartable getPoint(int n)

Description copied from interface: ChartModel

Gets the n^th point. The first point has index 0.

Specified by:

getPoint in interface ChartModel

Parameters:

n - the index

Returns:

the n^th point in the ChartModel.

getPointCount

public abstract int getPointCount()

Description copied from interface: ChartModel

Gets the number of points in the data set

Specified by:

getPointCount in interface ChartModel

Returns:

the number of points

update

protected abstract void update()

getName

public String getName()

Description copied from interface: ChartModel

The name of a ChartModel is important, as different chart models are assumed to have different names. If you're adding multiple models to a Chart, make sure they have different names.

Specified by:

getName in interface ChartModel

Specified by:

getName in interface Named

Returns:

a distinct name for this data set

setName

public void setName(String name)

getDelegate

public AnnotatedChartModel getDelegate()

getDelegate

public AnnotatedChartModel getDelegate(int i)

getDelegates

public AnnotatedChartModel[] getDelegates()

setDelegate

public void setDelegate(ChartModel chartModel)

setDelegates

public void setDelegates(Collection<ChartModel> chartModels,
                         boolean wireListeners)

setDelegates

public void setDelegates(ChartModel... chartModels)

isCyclical

public boolean isCyclical()

Cyclical models are quite rare so we return a value of false here

Specified by:

isCyclical in interface ChartModel

Returns:

whether the model represents a cycle of values

addChartModelListener

public void addChartModelListener(ChartModelListener listener)

Description copied from interface: ChartModel

Register the listener's interest in this chart model.

Specified by:

addChartModelListener in interface ChartModel

Parameters:

listener - the listener that will receive events

removeChartModelListener

public void removeChartModelListener(ChartModelListener listener)

Description copied from interface: ChartModel

De-register the listener's interest in this chart model.

Specified by:

removeChartModelListener in interface ChartModel

Parameters:

listener - the listener that will no longer receive events

fireModelChanged

protected void fireModelChanged()

chartModelChanged

public void chartModelChanged()

Specified by:

chartModelChanged in interface ChartModelListener

iterator

public Iterator<Chartable> iterator()

Specified by:

iterator in interface Iterable<Chartable>
