Interface IRangePolicy

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

ARangePolicy, RangePolicyFixedViewport, RangePolicyForcedPoint, RangePolicyHighestValues, RangePolicyHighestValuesForcedMin, RangePolicyMinimumViewport, RangePolicyUnbounded

public interface IRangePolicy
extends java.io.Serializable

An interface that allows an axis to be plugged with a range policy.

Implementations may limit the range of the underlying Chart2D's data (clipping / zooming), increase it (void space offset), guarantee a minimum viewport... .

Method Detail

addPropertyChangeListener

void addPropertyChangeListener(java.lang.String propertyName,
                               java.beans.PropertyChangeListener listener)

Registers a property change listener that will be informed about changes of the property identified by the given propertyName.

Parameters:

propertyName - the name of the property the listener is interested in

listener - a listener that will only be informed if the property identified by the argument propertyName changes

getMax

double getMax(double chartMin,
              double chartMax)

Define the upper bound of the Chart2D's value range. Depends on the AAxis this instance is bound to.

Parameters:

chartMin - the minimum value of the connected Chart2D that may / should be taken into account.

chartMax - the maximum value of the connected Chart2D that may / should be taken into account.

Returns:

the maximum value (upper bound) for the Chart2D to display.

getMin

double getMin(double chartMin,
              double chartMax)

Define the lower bound of the Chart2D's value range. Depends on the AAxis this instance is bound to.

Parameters:

chartMin - the minimum value of the connected Chart2D that may / should be taken into account.

chartMax - the maximum value of the connected Chart2D that may / should be taken into account.

Returns:

the minimum value (lower bound) for the Chart2D to display.

getPropertyChangeListeners

java.beans.PropertyChangeListener[] getPropertyChangeListeners(java.lang.String property)

Returns all property change listeners for the given property.

Parameters:

property - one of the constants with teh PROPERTY_ prefix defined in this class or subclasses.

Returns:

the property change listeners for the given property.

getRange

Range getRange()

Get the range of this range policy.

Returns:

he range of this range policy

removePropertyChangeListener

void removePropertyChangeListener(java.beans.PropertyChangeListener listener,
                                  java.lang.String property)

Deregisters a property change listener that has been registerd for listening on the given property.

Parameters:

listener - a listener that will only be informed if the property identified by the argument propertyName changes

property - the property the listener was registered to.

removePropertyChangeListener

void removePropertyChangeListener(java.lang.String property,
                                  java.beans.PropertyChangeListener listener)

Removes a property change listener for listening on the given property.

Parameters:

property - one of the constants with teh PROPERTY_ prefix defined in this class or subclasses.

listener - the listener for this property change.

setRange

void setRange(Range range)

Set the range of this RangePolicy.

Parameters:

range - the Range for the range policy.
