<p> 
  The data in an AO can be plotted using the <tt>iplot</tt> method.
</p>
<p>
  The <tt>iplot</tt> method provides an advanced plotting interface for AOs which tries to make good use of all the information
  contained within the input AOs. For example, if the <tt>xunits</tt> and <tt>yunits</tt> fields of the input AOs are set, these labels
  are used on the plot labels.
</p>

<p>
  In addition, <tt>iplot</tt> can be configured using a input <tt>plist</tt>. The following examples show some of the
  possible ways to use <tt>iplot</tt>
</p>

<div class="fragment"><pre>

</pre></div>
<p> Creates a time-series AO. If we look at the data object contained in this AO, we see that the <tt>xunits</tt>
are set to the defaults of seconds [s].</p>
<p>If we plot this object with <tt>iplot</tt> we see these units reflected in the x and y axis labels.</p>

<p>We also see that the time-origin of the data (<tt>t0</tt> field of the <tt>tsdata</tt> class) is displayed as the plot title.</p>
