When e.g. plotting the time signal $\exp(j \pi n)$ in the y[n] tab, the amplitude in the frequency view is twice the value it should be. For negative frequencies, the signal does not show up at all in the frequency view.
Workaround: Display two-sided spectra
Solution: Calculate the single-sided spectrum by adding negative and positive frequency components instead of simply scaling by two. This also takes care of correct DC-scaling.
