| 3 The data in an AO can be plotted using the <tt>iplot</tt> method. | |
| 4 </p> | |
| 5 <p> | |
| 6 The <tt>iplot</tt> method provides an advanced plotting interface for AOs which tries to make good use of all the information | |
| 7 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 | |
| 8 are used on the plot labels. | |
| 9 </p> | |
| 10 | |
| 11 <p> | |
| 12 In addition, <tt>iplot</tt> can be configured using a input <tt>plist</tt>. The following examples show some of the | |
| 13 possible ways to use <tt>iplot</tt> | |

| 57 <p>If we plot this object with <tt>iplot</tt> we see these units reflected in the x and y axis labels.</p> | |
