Method Detail

getTickPositions

public CoordinateMapping[] getTickPositions(double absoluteLength,
                                            double minDomainValue,
                                            double maxDomainValue,
                                            double tickDistance)

Calculates the mappings of the ticks according to the policy.

Overrides:

getTickPositions in class AscendingNumericTickPolicyStrategy

Parameters:

absoluteLength - the absolute length

minDomainValue - the minimal domain value

maxDomainValue - the maximal domain value

tickDistance - the absolute distance between to ticks

Returns:

the mappings of the ticks.

getTickPositions

public CoordinateMapping[] getTickPositions(int absoluteLength,
                                            int minDomainValue,
                                            int maxDomainValue,
                                            int tickDistance)

Calculates the mappings of the ticks according to the policy.

Overrides:

getTickPositions in class AscendingNumericTickPolicyStrategy

Parameters:

absoluteLength - the absolute length

minDomainValue - the minimal domain value

maxDomainValue - the maximal domain value

tickDistance - the absolute distance between to ticks

Returns:

the mappings of the ticks.

isMappingAllowed

public boolean isMappingAllowed()

Returns whether mapping and relabeling by MappingMethods should be allowed for the ticks of this PolicyStrategy. The default value is true. An example for allowed mapping would be the a logarithmic scaling. An example where a mapping (logarithmic or square root) does not make sense is the percentage policy.

Overrides:

isMappingAllowed in class PolicyStrategy

Returns:

true, if labels could be relabeled, false else.
