3D (time, scale, amplitude) plot in Continuous Wavelet Transform I will be extremely grateful if someone could please answer this basic question.
How can one plot a 3D  (translation, scale, amplitude) plot from the Continuous wavelet transform (CWT) coefficients?
The CWT coefficient is a M X N matrix. Which of the axis corresponds to the translation, scale and Magnitude.
Thanks for your help.
It suffices to use the translation and scale as $(X,Y)$ axes, and build some elevation map from the absolute values of the CWT (or the phase, the real or imaginary parts). A simple example in Matlab is:
load mtlb
scal = abs(cwt(mtlb,'bump',Fs));
mesh(scal)
axis tight
