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

computePreferredTickUnit

public double computePreferredTickUnit(double axisLength)

Computes the preferred tick unit based on the upper/lower bounds and the length of the axis in screen coordinates.

Specified by:

computePreferredTickUnit in class AbstractAxis

Parameters:

axisLength - the length in screen coordinates

Returns:

the tick unit

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

getValueForDisplay

public double getValueForDisplay(double displayPosition)

Get the data value for the given display position on this axis. If the axis is a CategoryAxis this will be the nearest value. -- cached double optimised version (shaves of 50% on delays)

Parameters:

displayPosition - A pixel position on this axis

Returns:

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

getZeroPosition in class AbstractAxis

Returns:

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

isValueOnAxis

public boolean isValueOnAxis(double value)

Checks if the given value is plottable on this axis

Specified by:

isValueOnAxis in interface Axis

getClassCssMetaData

public static java.util.List<javafx.css.CssMetaData<? extends javafx.css.Styleable,?>> getClassCssMetaData()

getCssMetaData

public java.util.List<javafx.css.CssMetaData<? extends javafx.css.Styleable,?>> getCssMetaData()

Description copied from class: AbstractAxisParameter

Specified by:

getCssMetaData in interface javafx.css.Styleable

Overrides:

getCssMetaData in class AbstractAxisParameter

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

getAxisTransform

public AxisTransform getAxisTransform()
