Constructor Detail

IntegerCoordinate

protected IntegerCoordinate(DataColumnSpec dataColumnSpec)

Constructor for class IntegerCoordinate.

Parameters:

dataColumnSpec - the column specification

Method Detail

getTickPositionsInternal

protected CoordinateMapping[] getTickPositionsInternal(double absoluteLength)

Returns an array with the positions of all ticks and their corresponding domain values given an absolute length. The pre-specified tick policy also influences the tick positions, e.g. ascending or descending.

Specified by:

getTickPositionsInternal in class NumericCoordinate

Parameters:

absoluteLength - the absolute length the domain is mapped on

Returns:

the mapping of tick positions and corresponding domain values

calculateMappedValueInternal

protected double calculateMappedValueInternal(DataCell domainValueCell,
                                              double absoluteLength)

Calculates a numeric mapping assuming a DoubleCell. Returns the mapping of a domain value for this coordinate axis. The mapping is done according to the given absolute length.

The value is not the position on the screen. Since the java coordinate system is upside down simply subtract the returned value from the screen height to calculate the screen position.

Specified by:

calculateMappedValueInternal in class NumericCoordinate

Parameters:

domainValueCell - the data cell with the domain value to map

absoluteLength - the absolute length on which the domain value is mapped on

Returns:

the mapped value

isMinDomainValueSet

public boolean isMinDomainValueSet()

Specified by:

isMinDomainValueSet in class NumericCoordinate

Returns:

true if the lower domain range is set properly

isMaxDomainValueSet

public boolean isMaxDomainValueSet()

Specified by:

isMaxDomainValueSet in class NumericCoordinate

Returns:

true if the upper domain range is set properly

setMinDomainValue

public void setMinDomainValue(double value)

Sets the lower domain value.

Overrides:

setMinDomainValue in class NumericCoordinate

Parameters:

value - the lower value

setMaxDomainValue

public void setMaxDomainValue(double value)

Sets the upper domain value.

Overrides:

setMaxDomainValue in class NumericCoordinate

Parameters:

value - the upper value
