Class TicLabelMap

java.lang.Object
  jcckit.plot.TicLabelMap

All Implemented Interfaces:

TicLabelFormat

public class TicLabelMap

extends java.lang.Object

implements TicLabelFormat

Map of number intervals onto a text label. The map is defined by a map description string provided by configuration data.

The map description is a list of conditions separated by ';'. The conditions are tested from left to right until a condition is fulfilled for the tic value. If no condition is fullfilled a '?' will be returned.

A condition description has one of the following forms:

<label>

<number>=<label>

<number1>:<number2>=<label>

The first type of condition is always fulfilled. It will return <label>. This is a kind of else condtion which is put at the end of the condition list.

The second form maps a particular number onto a label. In order to be equal with the sepcified number the tic value should not deviate more than 1 ppm (part per millions) from <number>.

The third form maps an interval onto a label. The condition reads

<number1> <= tic label < <number2>

Examples:

 1=monday;2=tuesday;3=wednesday;4=thursday;5=friday;6=saturday;7=sunday 
 0.5:1.5=I; 1.5:2.5 = II; 2.5:3.5 = III; the rest
