Scatter plots of relations between two variables (top) and their waveforms at the same time (bottom). MI and CC are given above the plots. Black grid lines correspond to the borders of the bins used to calculate MI. A given time step represents each sample of velocity data in a given time window and its associated sampling rate. a Two variables with the same sinusoidal waves. b Two variables with sinusoidal waves and a time shift. c One variable with a sinusoidal wave and one with a spike-like wave
