# 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.

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:
