waveform donut (cyclical measures as a torus)
Published:
wrapping around the axes of a univariate circular measure results in a polar plot. for a bivariate measure, this results in a torus 🍩. here, a waveform shape donut shows a fixed phase offset of a harmonic beta-component to a base alpha-oscillation. pic.twitter.com/ZvYauTFG06
