 [section:DiscreteAxis DiscreteAxis]
 
 A [*DiscreteAxis] is one of two optional refinements of the [link histogram.concepts.Axis [*Axis]] concept, the other one is the [link histogram.concepts.IntervalAxis IntervalAxis]. This concept is for values that do not form intervals, and for axes with intervals that contain exactly one value.
