title: Binary .dat file Plotting Column Array values
body: <p>I have imported an array into my IPython notebook using the following method:</p>
  
  <pre><code>SDSS_local_AGN = np.fromfile('/Users/iMacHome/Downloads/SDSS_local_AGN_Spectra.dat', dtype=float)
  </code></pre>
  
  <p>The array is of the form:</p>
  
  <pre><code> SPECOBJID_1         RA          DEC           SUBCLASS ...
   299528159882143744  146.29988   -0.12001413   AGN      ...
   299532283050747904  146.32957   -0.30622363   AGN      ...
  </code></pre>
  
  <p>Essentially each column has a header, and I now need to plot certain values.</p>
  
  <p>As an example, I want to plot RA against DEC...how would I go about doing this?</p>
  
  <p>Perhaps:</p>
  
  <pre><code>axScatter.plot(SDSS_local_AGN[RA], SDSS_local_AGN[DEC])
  </code></pre>
