Class Axis1D

  com.imsl.chart.AbstractChartNode
      com.imsl.chart.ChartNode
          com.imsl.chart.Axis1D

All Implemented Interfaces:

Serializable, Cloneable

public class Axis1D
extends ChartNode

An x-axis or a y-axis.

Axis1D is created by AxisXY as its child. It can be retrieved using the method AxisXY.getAxisX() or AxisXY.getAxisY().

It in turn creates the following child nodes: AxisLine, AxisLabel, AxisTitle, AxisUnit, MajorTick, MinorTick and Grid.

The number of tick marks ("Number" attribute) is set to 5, but autoscaling can change this value.

Method Detail

getAxisLabel

public AxisLabel getAxisLabel()

Returns the label node associated with this axis.

Returns:

the AxisLabel node created as a child by this node

getAxisLine

public AxisLine getAxisLine()

Returns the axis line node associated with this axis.

Returns:

the AxisLine node created as a child by this node

getAxisTitle

public AxisTitle getAxisTitle()

Returns the title node associated with this axis.

Returns:

the AxisTitle node created as a child by this node

getAxisUnit

public AxisUnit getAxisUnit()

Returns the unit node associated with this axis.

Returns:

the AxisUnit node created as a child by this node

getFirstTick

public double getFirstTick()

Convenience routine to get the "FirstTick" attribute.

Returns:

the double value of the "FirstTick" attribute, if defined. Otherwise, window[0] is returned.

getGrid

public Grid getGrid()

Returns the grid node associated with this axis.

Returns:

the Grid node created as a child by this node

getMajorTick

public MajorTick getMajorTick()

getMinorTick

public MinorTick getMinorTick()

Returns the minor tick node associated with this axis.

Returns:

the MinorTick node created as a child by this node

getTickInterval

public double getTickInterval()

Retrieves the tick interval.

Returns:

a double which specifies the tick interval

getTicks

public double[] getTicks()

Returns the value of the "Ticks" attribute, if set. If not set, then computed tick values are returned.

Returns:

the double value of the "Ticks" attribute, if defined. Otherwise, the computed tick values are returned.

getType

public int getType()

Returns the axis type.

Returns:

an int which specifies the node type; can be AXIS_X, AXIS_Y, AXIS_X_TOP or AXIS_Y_RIGHT

See Also:

AbstractChartNode.AXIS_X, AbstractChartNode.AXIS_Y, ChartNode.AXIS_X_TOP, ChartNode.AXIS_Y_RIGHT

getWindow

public double[] getWindow()

Returns the window for an Axis1D.

Returns:

a double array of length two containing the range of this axis.
