As illustrated on the tenth sample, the counter value changes from 0 to 1; hence calculated rate of
change is 1 per minute. At the thirteenth sample, the rate of change is 2 per minute. The rate of
change must be at least 3 per minute to exceed the event-triggering requirement of 2, which is met
on the eighteenth sample.

Figure 5
uses the same data to illustrate a case in which a threshold is exceeded without triggering
an event. In this case, the calculated rate of change in the data value is always less than or equal to
the high threshold of 2.
