Method Detail

formatKey

public java.lang.String formatKey(java.lang.Object key)

Description copied from interface: AxisMapper

Provides text representation of the coordinate value.

Parameters:

key - value in some coordinate space

Returns:

text representation of a coordinate value.

getPreferredHeight

public double getPreferredHeight(AbstractGraphics g,
                                 AbstractTextPainter textPainter)

Description copied from interface: AxisMapper

Gets preferred height.

Parameters:

g - graphics context

textPainter - text painter mode

Returns:

preferred height

getPreferredWidth

public double getPreferredWidth(AbstractGraphics g,
                                AbstractTextPainter textPainter)

Description copied from interface: AxisMapper

Gets preferred width.

Parameters:

g - graphics context

textPainter - text painter mode

Returns:

preferred width

getScale

public AxisScale getScale()

Description copied from interface: AxisMapper

Returns a scale object for this axis.

Returns:

scale object

getViewRange

public AxisMapperRange getViewRange()

Description copied from interface: AxisMapper

Gets an AxisMapperRange object representing visible axis range. The object can be used to set visible axis range. Returns normalized value from [0..1]

Returns:

AxisMapperRange object representing visible axis range

map

@Deprecated
public double map(java.lang.Object key)

Deprecated.

Description copied from interface: AxisMapper

Finds the position for the coordinate value.

Parameters:

key - value in some coordinate space

Returns:

a value in range [0,1]

setAxisCount

public void setAxisCount(int axisCount)

getAxisCount

public int getAxisCount()

Returns the number of axes in the chart. It is determined by calculating the maximum number of data values in each radar data model.

Returns:

number of axes in the chart

setInitAxisPosition

public void setInitAxisPosition(double angle)

Sets the initial rotation angle for axis (in radians).

Parameters:

angle - rotation angle in radians

getInitAxisPosition

public double getInitAxisPosition()

Returns the initial rotation angle for axis (in radians).

Returns:

double rotation in radians

map

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

Maps the polar values the polar point.

Parameters:

angle - angle of the polar coordinate

value - radius of the polar coordinate

Returns:

polar point in the polar coordinate system

mapAxis

public abstract 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.

Parameters:

index - radar axis index

value - position on the axis

Returns:

polar point in the polar coordinate system
