<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>
>> a1 = ao(plist(<span class="string">'tsfcn'</span>, <span class="string">'sin(2*pi*0.3*t) + randn(size(t))'</span>, <span class="string">'fs'</span>, 10, <span class="string">'nsecs'</span>, 20))

<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>
