title: Plot multidimensional vectors in Python
body: <p>I have a Matrix that contains N users and K items. I want to plot that matrix in Python by considering each line as a vector with multiple coordinates. For example a simple point plot require <code>X,Y</code>. My vector has<code>K</code> coordinates and I want to plot each one of those <code>N</code> vectors as a point to see there similarities. Can anyone help me with that ? </p>
  
  <p><strong>UPDATE:</strong></p>
  
  <pre><code>#Matrix M shape = (944, 1683)
  plt.figure()
  plt.imshow(M, interpolation='nearest', cmap=plt.cm.ocean)
  plt.colorbar()
  plt.show()
  </code></pre>
