title: Visualizing randomized four dimensional data set
body: <p>I have a four dimensional data set. None of the four variables are equally spaced. Right now, I visualize the data using 3D scatter (with the color of the dots indicating the fourth dimension). But this makes it extremely unwieldy while it is printed. Had the variables been evenly spaced,a series of pcolors would have been an option. Is there some way, wherein I can represent such a data using a series of 2D plots? My data set looks something like this:</p>
  
  <pre><code>   x = [3.67, 3.89, 25.6]
     y = [4.88, 4.88, 322.9]
     z = [1.0, 2.0, 3.0]
     b = [300.0,411.0,414.5]
  </code></pre>
