Method Detail

doMapping

DataCell doMapping(DataCell cell)

Maps the value according to its task.

Parameters:

cell - the value to map

Returns:

the mapped value

getLabel

double getLabel(DataCell cell)

Maps a value back to the original domain value for tick generation. Is the inverse function.

Parameters:

cell - the value

Returns:

the inverse value of cell according to this mapping

getDisplayName

String getDisplayName()

Returns the display name of this MappingMethod.

Returns:

the display name

isCompatibleWithDomain

Checks compatibility with a domain. Returns true by default.

Parameters:

domain - the domain

Returns:

true, if this mapping method is compatible.
