One of the most common questions that I am asked is this: Before
we describe the data in a graph, it is a good idea to identify
what a graph shows. This can usually be done in one simple
sentence. It is important to identify the different graph
elements before you construct this graph description sentence.
Look at the graph. What do you think it is important to include
in the graph description sentence? Remember that we are not
describing the data content of this graph yet. (more…) The verb
is to fluctuate. The noun is fluctuation. This is when the data
on a graph goes both up and down. The rises and falls may not be
regular but they are constant. The President’s popularity has
fluctuated during his term in office. There has been a constant
fluctuation in the President’s popularity over the last few
years
