As well as Difference, there are three other modes for displaying the graph data: Quotient, Proportional Increase and Proportional Decrease. Quotient is described in more detail in Permalink ‘04030500’ not found – both proportional increase and proportional decrease are new in STEM 7.5.
-
Proportional Increase: x/b – 1
-
Proportional Decrease: 1 – x/b
These new modes could be used to communicate how much more profitable various scenarios are relative to the base (or cheaper if using proportional decrease).
