FAQs

Must the intervals in an Interval Axis be adjacent?
No, there may be gaps between the intervals on a single Interval Axis. However, the intervals may not overlap and they must be in ascending order.

How are boundaries handled?
If a boundary point can belong to only one interval (that is, there is a gap on one side of the point), it is considered to lie in that interval. If a boundary point is simultaneously the upper bound of one interval and the lower bound of another, it belongs to the interval of which it is the minimal value.
