Real Morlet continuous wavelet transform with bipolar colormap

Using Wavelets.py from Pyscellania, this is a scalogram using the real Gabor-Morlet continuous wavelet transform, which is just a Gaussian-windowed real sinusoid. So as you drag the little blip of sinusoid along the data, it goes in and out of phase and cancels out, which is why it appears as a bunch of dots in a row.

 

This time I used a bipolar colormap to show positive and negative magnitude as the wavelet slides in and out of phase with the signal.
