Specified by:

computeRange in class AbstractAxis

Parameters:

min - The min data value that needs to be plotted on this axis

max - The max data value that needs to be plotted on this axis

axisLength - The length of the axis in display coordinates

getCssMetaData

public List<CssMetaData<? extends Styleable,?>> getCssMetaData()

Description copied from class: AbstractAxisParameter

Specified by:

getCssMetaData in interface Styleable

Overrides:

getCssMetaData in class AbstractAxisParameter

getDisplayPosition

public double getDisplayPosition(double value)

Get the display position along this axis for a given value. If the value is not in the current range, the returned value will be an extrapolation of the display position. -- cached double optimised version (shaves of 50% on delays)

Specified by:

getDisplayPosition in interface Axis

Overrides:

getDisplayPosition in class AbstractAxis

Parameters:

value - The data value to work out display position for

Returns:

display position

getLogarithmBase

public double getLogarithmBase()

Returns the value of the logarithmBaseProperty().

Returns:

base of the logarithm

getLogAxisType

public LogAxisType getLogAxisType()

Returns:

the log axis Type @see LogAxisType

getTickUnit

public double getTickUnit()

Returns tick unit value expressed in data units.

Specified by:

getTickUnit in interface Axis

Overrides:

getTickUnit in class AbstractAxisParameter

Returns:

major tick unit value

getTickUnitSupplier

public TickUnitSupplier getTickUnitSupplier()

Returns the value of the tickUnitSupplierProperty().

Returns:

the TickUnitSupplier

getValueForDisplay

the nearest data value to the given pixel position or null if not on axis;

getZeroPosition

public double getZeroPosition()

Get the display position of the zero line along this axis.

Specified by:

getZeroPosition in interface Axis

Overrides:

getZeroPosition in class AbstractAxis

Returns:

display position or Double.NaN if zero is not in current range;

isLogAxis

public boolean isLogAxis()

Description copied from interface: Axis

This is true when the axis implements a log scale

Returns:

true if logarithmic axis, false otherwise

isValueOnAxis

public boolean isValueOnAxis(double value)

Checks if the given value is plottable on this axis

Specified by:

isValueOnAxis in interface Axis

Overrides:

isValueOnAxis in class AbstractAxis

Parameters:

value - The value to check if its on axis

Returns:

true if the given value is plottable on this axis

logarithmBaseProperty

public DoubleProperty logarithmBaseProperty()

Base of the logarithm used by the axis, must be grater than 1.

Default value: 10

See Also:

getLogarithmBase(), setLogarithmBase(double)

requestAxisLayout

public void requestAxisLayout()

Description copied from class: AbstractAxis

Request that the axis is laid out in the next layout pass. This replaces requestLayout() as it has been overridden to do nothing so that changes to children's bounds etc do not cause a layout. This was done as a optimisation as the Axis knows the exact minimal set of changes that really need layout to be updated. So we only want to request layout then, not on any child change.

Specified by:

requestAxisLayout in interface Axis

Overrides:

requestAxisLayout in class AbstractAxis

setLogarithmBase

public void setLogarithmBase(double value)

Sets value of the logarithmBaseProperty().

Parameters:

Overrides:

setRange in class AbstractAxis

setTickUnit

public void setTickUnit(double unit)

Sets the value of the tickUnitProperty().

Specified by:

setTickUnit in interface Axis

Overrides:

setTickUnit in class AbstractAxisParameter

Parameters:

unit - major tick unit

setTickUnitSupplier

public void setTickUnitSupplier(TickUnitSupplier supplier)

Sets the value of the tickUnitSupplierProperty().

The value between each major tick mark in data units. This is automatically set if we are auto-ranging.

Specified by:

tickUnitProperty in interface Axis

Overrides:

tickUnitProperty in class AbstractAxisParameter
