Class AxisLinear<T extends IAxisScalePolicy>

java.lang.Object
  info.monitorenter.gui.chart.axis.AAxis<T>
      info.monitorenter.gui.chart.axis.AxisLinear<T>

Type Parameters:

T - Subtypes may be more picky which scale policies the accept to disallow incorrect scales: This supports it (see IAxis.setAxisScalePolicy(IAxisScalePolicy)).

All Implemented Interfaces:

IAxis<T>, java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener

Constructor Summary

AxisLinear()
Creates an instance that uses a LabelFormatterSimple for formatting numbers and a AxisScalePolicyAutomaticBestFit for controlling the scale.

AxisLinear(IAxisLabelFormatter formatter)
Constructor that uses the given label formatter for formatting labels.

AxisLinear(IAxisLabelFormatter formatter, T scalePolicy)
Constructor that uses the given label formatter for formatting labels along with the given scale policy.

Constructor Detail

AxisLinear

public AxisLinear()

Creates an instance that uses a LabelFormatterSimple for formatting numbers and a AxisScalePolicyAutomaticBestFit for controlling the scale.

AxisLinear

public AxisLinear(IAxisLabelFormatter formatter)

Constructor that uses the given label formatter for formatting labels.

Parameters:

formatter - needed for formatting labels of this axis.

AxisLinear

public AxisLinear(IAxisLabelFormatter formatter,
                  T scalePolicy)

Constructor that uses the given label formatter for formatting labels along with the given scale policy.

Parameters:

formatter - needed for formatting labels of this axis.

scalePolicy - controls the ticks/labels and their distance.

Method Detail

createAccessor

protected AAxis.AChart2DDataAccessor createAccessor(Chart2D chart,
                                                    int dimension,
                                                    int position)

Description copied from class: AAxis

Template method to create the proper AAxis.AChart2DDataAccessor implementation.

Specified by:

createAccessor in class AAxis<T extends IAxisScalePolicy>

Parameters:

chart - the chart to access.

dimension - Chart2D.X or Chart2D.Y.

position - Chart2D.CHART_POSITION_BOTTOM, Chart2D.CHART_POSITION_LEFT, Chart2D.CHART_POSITION_RIGHT or Chart2D.CHART_POSITION_TOP.

Returns:

the proper AAxis.AChart2DDataAccessor implementation.

AAxis.createAccessor(info.monitorenter.gui.chart.Chart2D, int, int)

getScaledValue

public double getScaledValue(double absolute)

Description copied from interface: IAxis

Scales the given absolute value into a value between 0 and 1.0 (if it is in the range of the data).

If the given absolute value is not in the display- range of the Chart2D, negative values or values greater than 1.0 may result.

Parameters:

absolute - a value in the real value range of the corresponding chart.

Returns:

a value between 0.0 and 1.0 that is mapped to a position within the chart.
