Active Notch Filter Simulation
This "simulator" does not seem to be very suited to simulate this kind of circuit. It looks like it can only do a time simulation. To see that 60 Hz is suppressed (it cannot be removed completely !) you would have to do many simulations and for many frequencies and plot the output's amplitude.

In a "real" circuit simulator like Qucs (free software !) or LTspice you can do an AC simulation which plots a figure like plot B in your question.
