Here Continuous Wavelet Transforms (CWTs) are computed with the 'wt' function of the R package 'biwavelet'.

Info

You might access different kinds of wavelet-related information:


Plot types

You might plot the wavelet information in 3 different ways.

  1. Info=f(x,T): plots the information according to location (x) and period (T).
  2. Info=f(x): plots the information according to location (x), for a certain value of period T0
  3. Power=f(T): plots power according to period (T). This information is averaged accross all locations x. For a given period T0, the range (light grey) and first and third quartiles (dark grey) of wavelet power coefficients are displayed.
