The meter-drawing method is defined for the Meter class, a subclass
of the View class. The meter class has three instance variables.
Three setters are defined for those variables for use in initialization:
Meter class definition View subclass: #Meter instanceVariableNames: 'min max title' classVariableNames: '' poolDictionaries: '' category: 'Experiment' Meter method definition • instance setMin: aNumber min := aNumber. Meter method definition • instance setMax: aNumber max := aNumber. Meter method definition • instance setTitle: aString title := aString.
