Answer 1

To supplement @Bence's answer, the additional vertical colorbar can be added using a snippet of code from here. Specifically, I used the following code, where 'xxx' is my data set, where each layer shown in Bence's plot is a separate z layer in a dstack'd numpy array. :

m = cm.ScalarMappable(cmap=cm.jet)
m.set_array(xxx)
pyplot.colorbar(m)
pyplot.show()
