There are two implementations provided and you are free to implement your own if you do not like the default implementations provided. Field Summary protected  double increment      Method Summary abstract protected  void computeIncrement()      Computes the scale increment. final public  void computeScaleValues()      Drives the computation of the axis increment and related values taking into account the user specified rounding criteria. final public  double getIncrement()      final public  double getMaxValue()      final public  double getMinValue()      public  int getNumberOfScaleItems()      final public  int getRoundingPowerOfTen()      protected  double round(double value, double powerOfTen)      Rounds the passed value by the power of ten specified Parameters:   value - the value to round Parameters:   powerOfTen - the product of 10 times the rounding property. protected  void roundTheIncrement(double powerOfTen)      Rounds the scale increment up by the power of ten specified in the properties. final public  void setMaxValue(double maxValue)      final public  void setMinValue(double minValue)      public  void setNumberOfScaleItems(int numberOfScaleItems)      final public  void setRoundingPowerOfTen(int powerOfTen)      Sets the exponent power of ten to round values to. public  String toString()      Field Detail increment protected double increment(Code) Method Detail computeIncrement abstract protected void computeIncrement()(Code) Computes the scale increment. computeScaleValues final public void computeScaleValues()(Code) Drives the computation of the axis increment and related values taking into account the user specified rounding criteria. So if you specify to round to the nearest 100 and give an increment of 2.5, the increment will become 100. getIncrement final public double getIncrement()(Code) getMaxValue final public double getMaxValue()(Code) getMinValue final public double getMinValue()(Code) getNumberOfScaleItems public int getNumberOfScaleItems()(Code) getRoundingPowerOfTen final public int getRoundingPowerOfTen()(Code) round protected double round(double value, double powerOfTen)(Code) Rounds the passed value by the power of ten specified Parameters:   value - the value to round Parameters:   powerOfTen - the product of 10 times the rounding property. double the rounded result roundTheIncrement protected void roundTheIncrement(double powerOfTen)(Code) Rounds the scale increment up by the power of ten specified in the properties. Parameters:   powerOfTen - the value of 10 times the rounding property. setMaxValue final public void setMaxValue(double maxValue)(Code) setMinValue final public void setMinValue(double minValue)(Code) setNumberOfScaleItems public void setNumberOfScaleItems(int numberOfScaleItems)(Code) setRoundingPowerOfTen final public void setRoundingPowerOfTen(int powerOfTen)(Code) Sets the exponent power of ten to round values to. Parameters:   powerOfTen - exponent of ten to round to: 1=10, 2=100, -2=.01 toString public String toString()(Code) String Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
