3D (time, scale, amplitude) plot in Continuous Wavelet Transform
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
