What is a fluctuating trend, and how do I summarise it?
A fluctuation is when numbers go up and down and up and down. In other words, up down up down is a fluctuation. Just one up and one down is not a fluctuation.
Summarise a fluctuating trend in a details paragraph by giving the range for each axis. For example:
The percentage of visitors who went to the Pier fluctuated between about 4% and just below 14% between 1980 and 2000
