Now you will see the graph equation expressed as a table of values enclosed in parentheses. These values could have been typed in directly, but instead we generated them in the Graph Lookup Editor.
| Ø | Add the units Dmnl (for Dimensionless, which you could also have typed in) to the Units editing box, then click OK to close the Equation Editor. |
The units Dimensionless are pretty important to understand. When we normalized the input to the Lookup, we divided the Rabbit Population (measured in rabbits) by carrying capacity (also measured in rabbits) leaving a dimensionless variable.
