This is the value of the slopegraph. It allows us to make a whole host of point-to-point com-
parisons, and the largest magnitude changes literally jump to the surface.
Summary
In this chapter, we took a close look at a number of different ways to show quantities and
events over time. We considered simple line plots, dual-axis line plots, connected scatter-
plots, different levels of aggregation, forecasts, timelines, and finally slopegraphs.
In the next chapter, we'll move from time to the other ubiquitous element of our universe:
space.
