5.4.2 Operations

Graphs can be displayed in several different ways for comparison. The default mode is None. Each operation is described in more detail below.

None: This default mode displays the raw graph data using the Type and Style of graph defined in the configuration.

Difference: this mode displays the graph data in a format that shows the differences between the elements/scenarios selected for drawing. The element/scenario selected in the Base drop-down list box is used as the base against which the other element(s)/scenario(s) are compared.

Quotient: this mode displays the graph data as a proportion using the element/scenario selected in the Base drop-down list box as the base element/scenario against which all the others are compared.

Proportional Increase: x/b – 1

Proportional Decrease: 1 – x/b

Proportional Increase and Proportional Decrease were introduced in STEM 7.5 and could be used, for example, to communicate how much more profitable various scenarios are relative to the base (or cheaper if using proportional decrease).
