It would be handy to be able to construct 3-D plots like http://matplotlib.org/examples/mplot3d/wire3d_zero_stride.html
So, for example I can view daily activity for a particular stock as a single line, and stack 30 of these lines next one another -- the resulting surface might pick up day to day patterns/cycles.
from mpl_toolkits.mplot3d import axes3d fails with: InputRejected:
Importing axes3d from mpl_toolkits.mplot3d raised an ImportError. No modules or attributes with a similar name were found.
It might be worthwhile for Quantopian to look at leveraging https://gitgud.io/unconed/mathbox -- that would allow for state-of-the-art dynamic data visualisation.
