Time domain graph

I read with interest Agilent application note AN 1287-8 which describes a method of filter adjustment using TDR to define both tuning and coupling in a simple manner. The method relies on the generation of S11 in log mag format against time, and I'd like to know how to achieve this in Genesys. In graph properties I have tried using "db(ifft(s11))" as the Y variable, but this seems to confuse the X axis, and nothing useful results. Can anyone tell me how the results in the paper might be achieved?
