title: 3D-Stacked 2D histograms in matplotlib pyplot
body: <p>I have a bunch of 2D histograms (square 2D numpy arrays) that I want to stack in 3D like so:</p>

  <p>Does anyone have any good ideas how to do this? I've already tried the contourf approach from <a href="https://stackoverflow.com/questions/15582105/python-plot-stacked-image-slices">Python plot - stacked image slices</a>, but the result is less than optimal.</p>
  
  <p>Thanks.</p>
