  • 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 class Parent

  • 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

    public void invalidateRange(List<T> data)

    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

    protected abstract Object autoRange(double length)

    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

    protected abstract void setRange(Object range,
                                     boolean animate)

    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()

  • getRange

    protected abstract Object 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

    public abstract double getDisplayPosition(T 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. 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

    public abstract T 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.

    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

    public abstract boolean isValueOnAxis(T value)

    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

    public abstract double toNumericValue(T value)

    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

    public abstract T toRealValue(double value)

    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

    protected abstract List<T> calculateTickValues(double length,
                                                   Object range)

    Calculate a list of all the data values for each tick mark in range

    Parameters:

    length - The length of the axis in display units

    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 class Region

    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 class Region

    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 class Parent

  • getTickMarkLabel

    protected abstract String getTickMarkLabel(T value)

    Get the string label name for a tick mark with the given value

    Parameters:

    value - The value to format into a tick label string

    Returns:

    A formatted string for the given value

  • measureTickMarkLabelSize

    protected final Dimension2D measureTickMarkLabelSize(String labelText,
                                                         double rotation)

    Measure the size of the label for given tick mark value. This uses the font that is set for the tick marks

    Parameters:

    labelText - tick mark label text

    Returns:

    size of tick mark label for given value

  • measureTickMarkSize

    protected final Dimension2D measureTickMarkSize(T value,
                                                    double rotation)

    Measure the size of the label for given tick mark value. This uses the font that is set for the tick marks

    Parameters:

    value - tick mark value

    Returns:

    size of tick mark label for given value

  • measureTickMarkSize

    protected Dimension2D measureTickMarkSize(T value,
                                              Object range)

    Measure the size of the label for given tick mark value. This uses the font that is set for the tick marks

    Parameters:

    value - tick mark value

    Returns:

    size of tick mark label for given value

  • getClassCssMetaData

    public static List<CssMetaData<? extends Styleable,?>> getClassCssMetaData()

    Returns:

    The CssMetaData associated with this class, which may include the CssMetaData of its super classes.

    Since:

    JavaFX 8.0

  • getCssMetaData

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

    This method should delegate to Node.getClassCssMetaData() so that a Node's CssMetaData can be accessed without the need for reflection.

    Specified by:

    getCssMetaData in interface Styleable

    Overrides:

    getCssMetaData in class Region

    Returns:

    The CssMetaData associated with this node, which may include the CssMetaData of its super classes.

    Since:

    JavaFX 8.0
