1. Single spectrum
Power in dB on the Y axis, frequency on the X axis.
Power Spectrum to 3D DSA EEG
Start with one power spectrum, repeat it over time, then stack the spectra into a rotatable 3D DSA surface.

3. DSA as a 3D surface
X = frequency, Y = time, height and color = power. Click and drag on the graph to rotate.
