Method Detail

bindBounds

public static void bindBounds(ValueAxis<?> axis,
                              ValueAxis<?> observable)

Binds lower and upper bound of given axis to the specified observable axis.

Parameters:

axis - axis whose lower/upper bound should be bound

observable - the target axis

Throws:

NullPointerException - if either axis is null TODO: found bug if axis and observable axis are slightly different (e.g. one longer or shifted w.r.t. the other) This function the forces the axis of observable (basechart) even if the 'axis' extends beyond that

hasBoundedRange

public static boolean hasBoundedRange(Axis axis)

Indicates if the given axis lower and/or upper bound property is bound.

Parameters:

axis - the tested axis

Returns:

true if either lower or upper bound is bound

hasBoundedRange

public static boolean hasBoundedRange(ValueAxis<?> axis)

Indicates if the given axis lower and/or upper bound property is bound.

Parameters:

axis - the tested axis

Returns:

true if either lower or upper bound is bound

isCategoryAxis

public static boolean isCategoryAxis(Axis axis)

Returns true if given axis is an instance of CategoryAxis.

Parameters:

axis - the axis to test

Returns:

true if given axis is an instance of CategoryAxis.

unbindBounds

public static void unbindBounds(ValueAxis<?> axis)

Unbinds lower and upper bound of given axis.

Parameters:

axis - axis whose lower and upper bound should be unbound

Throws:

NullPointerException - if the given axis is null
