public abstract class Axis<T> extends Region
Base class for all axes in JavaFX that represents an axis drawn on a chart area.
It holds properties for axis auto ranging, ticks and labels along the axis.
Some examples of concrete subclasses include NumberAxis
whose axis plots data
in numbers and CategoryAxis
whose values / ticks represent string
categories along its axis.
- Since:
- JavaFX 2.0

isRangeValid
protected final boolean isRangeValid()See if the current range is valid, if it is not then any range dependent calulcations need to redone on the next layout pass- Returns:
- true if current range calculations are valid
-
invalidateRange
protected final void invalidateRange()Mark the current range invalid, this will cause anything that depends on the range to be recalculated on the next layout. -
shouldAnimate
protected final boolean shouldAnimate()This is used to check if any given animation should run. It returns true if animation is enabled and the node is visible and in a scene.- Returns:
- true if animations should happen
-
requestLayout
public void requestLayout()We suppress requestLayout() calls here by doing nothing as we don't want changes to our children to cause layout. If you really need to request layout then call requestAxisLayout().- Overrides:
requestLayout
in classParent
-
requestAxisLayout
public void requestAxisLayout()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 optimization 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. -
invalidateRange
Called when data has changed and the range may not be valid any more. This is only called by the chart if isAutoRanging() returns true. If we are auto ranging it will cause layout to be requested and auto ranging to happen on next layout pass.- Parameters:
data
- The current set of all data that needs to be plotted on this axis
-
autoRange
This calculates the upper and lower bound based on the data provided to invalidateRange() method. This must not effect the state of the axis, changing any properties of the axis. Any results of the auto-ranging should be returned in the range object. This will we passed to setRange() if it has been decided to adopt this range for this axis.- Parameters:
length
- The length of the axis in screen coordinates- Returns:
- Range information, this is implementation dependent
-
setRange
Called to set the current axis range to the given range. If isAnimating() is true then this method should animate the range to the new range.- Parameters:
range
- A range object returned from autoRange()animate
- If true animate the change in range
-
getRange
Called to get the current axis range.- Returns:
- A range object that can be passed to setRange() and calculateTickValues()
-
getZeroPosition
public abstract double getZeroPosition()Get the display position of the zero line along this axis.- Returns:
- display position or Double.NaN if zero is not in current range;
-
getDisplayPosition
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. If the value is not valid for this Axis and the axis cannot display such value in any range, Double.NaN is returned- Parameters:
value
- The data value to work out display position for- Returns:
- display position or Double.NaN if value not valid
-
getValueForDisplay
Get the data value for the given display position on this axis. If the axis is a CategoryAxis this will be the nearest value.- Parameters:
displayPosition
- A pixel position on this axis- Returns:
- the nearest data value to the given pixel position or null if not on axis;
-
isValueOnAxis
Checks if the given value is plottable on this axis- Parameters:
value
- The value to check if its on axis- Returns:
- true if the given value is plottable on this axis
-
toNumericValue
All axis values must be representable by some numeric value. This gets the numeric value for a given data value.- Parameters:
value
- The data value to convert- Returns:
- Numeric value for the given data value
-
toRealValue
All axis values must be representable by some numeric value. This gets the data value for a given numeric value.- Parameters:
value
- The numeric value to convert- Returns:
- Data value for given numeric value
-
calculateTickValues
Calculate a list of all the data values for each tick mark in range- Parameters:
length
- The length of the axis in display unitsrange
- A range object returned from autoRange()- Returns:
- A list of tick marks that fit along the axis if it was the given length
-
computePrefHeight
protected double computePrefHeight(double width)Computes the preferred height of this axis for the given width. If axis orientation is horizontal, it takes into account the tick mark length, tick label gap and label height.- Overrides:
computePrefHeight
in classRegion
- Parameters:
width
- the width that should be used if preferred height depends on it- Returns:
- the computed preferred width for this axis
-
computePrefWidth
protected double computePrefWidth(double height)Computes the preferred width of this axis for the given height. If axis orientation is vertical, it takes into account the tick mark length, tick label gap and label height.- Overrides:
computePrefWidth
in classRegion
- Parameters:
height
- the height that should be used if preferred width depends on it- Returns:
- the computed preferred width for this axis
-
tickMarksUpdated
protected void tickMarksUpdated()Called during layout if the tickmarks have been updated, allowing subclasses to do anything they need to in reaction. -
layoutChildren
protected void layoutChildren()Invoked during the layout pass to layout this axis and all its content.- Overrides:
layoutChildren
in classParent

getTickMarkLabel
Get the string label name for a tick mark with the given value- Parameters:
value
