The S-Gate applies an imaginary unit multiplication to |0> state.

The complex number Quantum Possilitity Space is different after the S-Gate however probability, equal to the square of QPS magnitude, is unchanged. As a result, the plot of state probabilities is visually similar to the previous tab 'CNOT'.
