The equations behind the various plotting options in the Direct Plot form are detailed in the SpectreRF User Guide Appendix E. Plotting S-Parameter Simulation Data. Theoretically, the equations accessed via the direct plot form should be the same as those accessed via the calculator/results browser.
Note that there are some caveats to watch out for...e.g., when you plot GT (transducer gain), there is an assumption made that Gamma-L and Gamma-S are zero. Which means you are basically plotting |S21|^2
