public interface ChartModel
extends Named, Iterable<Chartable>

This is the main interface for the models supported by the Chart component. As a convenience to the user of this model, we extend Iterable<Chartable> so that the user can easily iterate over the chartable points that the model contains.

Chart.setModel(ChartModel), Chart.addModel(ChartModel)

Method Summary

String	getName() The name of a ChartModel is important, as different chart models are assumed to have different names.
Chartable	getPoint(int n) Gets the nth point.
int	getPointCount() Gets the number of points in the data set
boolean	isCyclical() Should a line be drawn from the last to the first point?

Method Detail

getName

String getName()

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 Named

Returns:

a distinct name for this data set

getPoint

Chartable getPoint(int n)

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

Parameters:

n - the index

Returns:

the n^th point in the ChartModel.

getPointCount

int getPointCount()

Gets the number of points in the data set

Returns:

the number of points

isCyclical

boolean isCyclical()

Should a line be drawn from the last to the first point?

Returns:

whether the model represents a cycle of values

addChartModelListener

void addChartModelListener(ChartModelListener listener)

Register the listener's interest in this chart model.

Parameters:

listener - the listener that will receive events

removeChartModelListener

void removeChartModelListener(ChartModelListener listener)

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

Parameters:

listener - the listener that will no longer receive events
