Constructor Detail

RadarMapper

public RadarMapper(AxisMapper axisMapper)

Constructs a new radar mapper object.

Parameters:

axisMapper - An axis mapper object used to map data values on each radar axis.

Method Detail

map

public PolarPoint map(java.lang.Double angle,
                      java.lang.Object value)

Maps the polar values the polar point.

Specified by:

map in class AbstractRadarMapper

Parameters:

angle - angle of the polar coordinate

value - radius of the polar coordinate

Returns:

polar point in the polar coordinate system

mapAxis

public PolarPoint mapAxis(java.lang.Integer index,
                          java.lang.Object value)

Maps the point on the specified radar axis to the polar point, when the relative position on the radar axis is already known.

Specified by:

mapAxis in class AbstractRadarMapper

Parameters:

idx - radar axis index

value - position on the axis

Returns:

polar point in the polar coordinate system

mapAxis

public PolarPoint mapAxis(java.lang.Integer index,
                          java.lang.Double value,
                          PolarPoint pp)

Maps the point on the specified radar axis to the polar point, when the relative position on the radar axis is already known.

Parameters:

idx - radar axis index

value - position on the axis

Returns:

polar point in the polar coordinate system
