Detailed Description

Represents an axis of a chart encapsulated by an instance of XYChart.

Axis uses the JFreeChart class NumberAxis to store some axis properties. This class represents the \(x\)-axis or the \(y\)-axis of a XYChart and, consequently, is drawn when calling the toLatex method. It provides tools to customize the axis in modifying labels and description.

Constructor & Destructor Documentation

Axis()

Axis	(	NumberAxis	inAxis,
		boolean	orientation
	)

Create a new Axis instance from an existing NumberAxis instance with vertical ( \(y\)-axis) or horizontal ( \(x\)-axis) orientation.

Parameters

inAxis	NumberAxis instance associated to the new variable.
orientation	axis direction, horizontal or vertical

Member Function Documentation

getAxis()

NumberAxis getAxis ( )

protected

Returns the NumberAxis instance (from JFreeChart) linked with the current variable.

Returns

the NumberAxis instance (from JFreeChart) linked with the current variable.

getLabel()

String getLabel

(

)

Returns the axis description.

Returns

the axis description.

getTwinAxisPosition()

double getTwinAxisPosition

(

)

Returns the drawing position parameter (default equals 0).

Returns

drawing position parameter.

setLabel()

void setLabel

(

String

label

)

Sets the axis description.

This description will be displayed on the chart, near the axis.

Parameters

label

axis label.

setLabels() [1/3]

void setLabels

(

double

tick

)

Sets a periodic label display.

Labels will be shown every tick unit. This tick unit replaces the default unit.

Parameters

tick	tick unit.

setLabels() [2/3]

void setLabels

(

double []

position

)

Sets the position of each label on this axis.

This method requires an array containing an increasing sequence of numbers representing the positions at which labels will appear on the axis. It is designed to export the axis to a LaTeX source code; it has no effect on the chart appearance displayed with XYChart.view().

Parameters

position

new label positions.

setLabels() [3/3]

void setLabels	(	double []	position,
		String []	label
	)

Assigns custom labels to user-defined positions on the axis.

This method requires an array of positions as well as an array of labels. The label label[i] will be used at position position[i]. It is designed to export the axis to a LaTeX source code, and to use LaTeX/TikZ commands to write prettier characters; it has no effect on the chart appearance displayed with XYChart.view().

Parameters

position	label series position on the axis.
label	label series name on the axis.

setTwinAxisPosition()

void setTwinAxisPosition

(

double

position

)

Defines where the opposite axis must be drawn on the current axis, where it should appear, and on which label.

Parameters

position

new drawing position.

toLatex()

String toLatex

(

double

scale

)

Formats and returns a string containing a LaTeX-compatible source code which represents this axis and its parameters.

Returns

LaTeX source code in a String.

Parameters

scale

current axis wished scale.
