For pivoting (creating series), only allow for nominal output variables or input variables. Input variables selected for the x-axis can be treated as either nominal or ratio. If selected for the y-axis, they are treated as ratio. If a non-axis variable (which means they are at least the 3rd selected variable), they are treated as nominal and can cause additional series to be created.
