Connecting the data points on the line chart implies that all the intermediate values not only exist, but actually occurred...At some point late Monday, Christopher saw 8.3 pairs of red pants.
I would be better to use continuous data like temperature, speed or altitude. If Christopher climbs Mt. Washington, and at 1:00 he is at 4,000 feet and at 2:00 he is at 5,000 feet we can be sure that at some point he was at every altitude between 4 and 5 thousand feet.
