Method Detail

calcValuesByTickNumber

public void calcValuesByTickNumber(int tickNumber,
                                   int minorTickNumber)

Description copied from class: TickCalculator

Calculate the tick values by the given tick number and minor ticks number. The minor ticks number is a proposed value, and may be different from actual minor ticks number returned by TickCalculator.getMinorNumber().

Specified by:

calcValuesByTickNumber in class TickCalculator

minorTickNumber - if the given number is TickCalculator.AUTO_MINORTICK_NUMBER, the tick number is automatically chosen.

calcValuesByTickInterval

public void calcValuesByTickInterval(double interval,
                                     double offset,
                                     int minorTickNumber)

Description copied from class: TickCalculator

Calculate the tick values by the given interval and minor ticks number. The minor ticks number is a proposed value, and may be different from actual minor ticks number returned by TickCalculator.getMinorNumber().

Specified by:

calcValuesByTickInterval in class TickCalculator

minorTickNumber - if the given number is TickCalculator.AUTO_MINORTICK_NUMBER, the tick number is derived from interval.

getInterval

public double getInterval()

Specified by:

getInterval in class TickCalculator

Returns:

the tick interval.

getMinorNumber

public int getMinorNumber()

Specified by:

getMinorNumber in class TickCalculator

Returns:

the actual minor tick number.

getValues

public double[] getValues()

Specified by:

getValues in class DoubleTickCalculator

Returns:

the tick values

getMinorValues

public double[] getMinorValues()

Specified by:

getMinorValues in class DoubleTickCalculator

Returns:

the minor tick values

calcLabelTextFormat

public java.text.Format calcLabelTextFormat(java.lang.Object canonicalValues)

Description copied from class: TickCalculator

Calculate a proper text format to format the labels on given values. A calculator can just returns a text format and do not provide a format string (returns a empty string). If The returned text format is null, a proper format string must be provided.

Specified by:

calcLabelTextFormat in class TickCalculator

Returns:

a text format object

getLabelFormate

public java.lang.String getLabelFormate()

Description copied from class: TickCalculator

Returns a proper format string to format the labels on ticks values returned by TickCalculator.getValues(). Some calculator can derive format from its internal status directly.

Specified by:

getLabelFormate in class TickCalculator
