Constructor Detail

AbstractFormatter

public AbstractFormatter()

AbstractFormatter

public AbstractFormatter(Axis axis)

Construct a DefaultFormatter for the given NumberAxis

Parameters:

axis - The axis to format tick marks for

Method Detail

getLogRange

protected double getLogRange()

getRange

protected double getRange()

getTickUnitSupplier

public TickUnitSupplier getTickUnitSupplier()

Returns the value of the tickUnitSupplierProperty().

Specified by:

getTickUnitSupplier in interface AxisLabelFormatter

Returns:

the TickUnitSupplier

rangeUpdated

protected abstract void rangeUpdated()

schmittTriggerThresholdProperty

public javafx.beans.property.DoubleProperty schmittTriggerThresholdProperty()

sets the min/max threshold when to change from one formatter domain to the other

Returns:

the Schmitt trigger threshold property

setTickUnitSupplier

public void setTickUnitSupplier(TickUnitSupplier supplier)

Sets the value of the tickUnitSupplierProperty().

Specified by:

setTickUnitSupplier in interface AxisLabelFormatter

Parameters:

supplier - the tick unit supplier. If null, the default one will be used

tickUnitSupplierProperty

public javafx.beans.property.ObjectProperty<TickUnitSupplier> tickUnitSupplierProperty()

Strategy to compute major tick unit when auto-range is on or when axis bounds change. By default initialised to DefaultTickUnitSupplier.

See TickUnitSupplier for more information about the expected behaviour of the strategy.

Specified by:

tickUnitSupplierProperty in interface AxisLabelFormatter

Returns:

tickUnitSupplier property

updateFormatter

public void updateFormatter(java.util.List<java.lang.Double> newMajorTickMarks,
                            double unitScaling)

Description copied from interface: AxisLabelFormatter

Called just before new TickMarks are computed

Specified by:

updateFormatter in interface AxisLabelFormatter

Parameters:

newMajorTickMarks - for which the labels should be computed

unitScaling - scaling applied to the raw data set units
