  - autoRange
```
protected AxisRange 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
  - autoRange
```

                              double labelSize)
```
    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(). TODO: re-enable

    Calculate a list of all the data values for each tick mark in range
    
    Parameters:
    
    length - The length of the axis in display units

    Calculate a new scale for this axis. This should not effect any state(properties) of this axis.
    
    Parameters:
    
    length - The display length of the axis
    
    lowerBound - The lower bound value
    
    upperBound - The upper bound value

    axisLength - the length in screen coordinates
    
    Returns:
    
    the tick unit
  - 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
    
    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
    
    Returns:
    
    the computed preferred width for this axis

                                          double labelSize)
```
    Computes range of this axis, similarly to autoRange(double, double, double, double). The major difference is that this method is called when auto-range is off.
    
    Parameters:
    
    minValue - The min data value that needs to be plotted on this axis
    
    maxValue - The max data value that needs to be plotted on this axis
    
    axisLength - The length of the axis in display coordinates
    
    labelSize - The approximate average size a label takes along the axis
    
    Returns:

    fireInvalidated in class AbstractAxisParameter
  - forceRedraw
```
public void forceRedraw()
```
    Description copied from interface: Axis
    
    forces redrawing of axis (via layoutChildren()). This is used to force an update while the main chart area is being updated (a requestLayout()) would be executed only during the next pulse. This is used explicitly in the Chart class. Outside use of this context should be limited to a minimum... handle with care
    
    Specified by:
    
    forceRedraw in interface Axis

    Specified by:
    
    getDisplayPosition in interface Axis
    
    Parameters:
    
    value - The data value to work out display position for

public TickMark getNewTickMark(Double tickValue,
                               Double tickPosition,
                               String tickMarkLabel)
```
  - getTickMarkLabel
```
public String getTickMarkLabel(double value)
```
    Get the string label name for a tick mark with the given value
    
    Specified by:
    
    getTickMarkLabel in interface Axis
    
    Parameters:
    
    value - The value to format into a tick label string
    
    Returns:
    
    A formatted string for the given value
  - getZeroPosition
```
public double getZeroPosition()
```
    Get the display position of the zero line along this axis.
    
    Specified by:
    
    getZeroPosition in interface Axis
    
    Returns:
    
    display position or Double.NaN if zero is not in current range;
  - invalidateRange
```
protected void invalidateRange()
```
    Mark the current range invalid, this will cause anything that depends on the range to be recalculated on the next layout.
    
    Overrides:
    
    invalidateRange in class AbstractAxisParameter
  - invalidateRange
```
public void invalidateRange(List<Number> 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.
    
    Specified by:
    
    invalidateRange in interface Axis
    
    Parameters:
    
    data - The current set of all data that needs to be plotted on this axis
  - isLabelOverlapping
```
public boolean isLabelOverlapping()
```
  - isRangeValid
```
protected boolean isRangeValid()
```
    See if the current range is valid, if it is not then any range dependent calculations need to redone on the next layout pass
    
    Returns:
    
    true if current range calculations are valid
  - isValueOnAxis
```
public boolean isValueOnAxis(double value)
```
    Checks if the given value is plottable on this axis
    
    Specified by:
    
    isValueOnAxis in interface Axis
    
    Parameters:
    
    value - The value to check if its on axis
    
    Returns:
    
    true if the given value is plottable on this axis
  - layoutChildren
```
protected void layoutChildren()
```
    Invoked during the layout pass to layout this axis and all its content.
    
    Overrides:
    
    layoutChildren in class Parent
  - measureTickMarkLength
```
protected double measureTickMarkLength(double major)
```
  - recomputeTickMarks
```
public void recomputeTickMarks()
```
  - recomputeTickMarks
```
protected void recomputeTickMarks(AxisRange range)
```
  - 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 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
  - setAxisLabelFormatter
```
public void setAxisLabelFormatter(AxisLabelFormatter value)
```

    Specified by:
    
    setMin in interface AxisDescription

    setMin in class AbstractAxisParameter
  - setRange
```
protected void setRange(AxisRange rangeObj,
                        boolean animate)
```
  - shouldAnimate
```
protected 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
  - tickMarksUpdated
```
protected void tickMarksUpdated()
```
    Called during layout if the tickmarks have been updated, allowing subclasses to do anything they need to in reaction.
  - updateCachedVariables
```
protected void updateCachedVariables()

    Parameters:
    
    coordinate - double coordinate to snapped to actual pixel index
    
    Returns:
    
    coordinate that is snapped to pixel (for a 'crisper' display)
