Time/frequency color map in python

Is there in native Python 3.X library or in scipy/numpy/matplolib libraries a function or their short set which could help me to draw a plot similar to this one(?):

enter image description here

What would be an efficient way to achieve something like this? Thank you in advance.

Answer

The bottom plot is the result of Continuous Wavelet Transform. There is a function called cwt() in Scipy. Check it out here. http://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.cwt.html
