title: How to plot a data cube in python
body: <p>I was wondering if there's a way to plot a data cube in Python. I mean I have three coordinate for every point</p>
  
  <pre><code>x=part.points[:,0]
  y=part.points[:,1]
  z=part.points[:,2]
  </code></pre>
  
  <p>And for every point I have a scalar field t(x,y,z)</p>
  
  <p>I would like to plot a 3D data cube showing the position of the point and for every point a color which is proportional to the scalar field t in that point.</p>
  
  <p>I tried with histogramdd but it didn't work.</p>
