147	<p>
148	The Gantt chart can be adjusted by dragging the bars left or right, or the events can be resized if you place the cursor at the
149	right edge of the event. To get the details of the bar being dragged you can use the
150	<i>onadjustend</i> event, and in that you can look at the RGraph registry - <i>RGraph.Registry.Get('chart.adjusting.gantt')</i> The
151	returned array consists of:
152
153	<ul>
154	<li>The numerical index of the event being adjusted (corresponding to the chart.events array that you set).</li>
155	<li>The chart object</li>
156	<li>The starting X position of the bar (before the chart was adjusted)</li>
157	<li>The starting Y position of the bar (before the chart was adjusted)</li>
158	<li>The original numerical value (in relation to your chart.xmax) that the bar started at</li>
159	</ul>
160	</p>
161
162	<p>
163	When adjusting is complete the <i>chart.events</i> array is updated. So you can use the numerical index that you find in
164	the registry (as above) with the <i>chart.events</i> array to get up-to-date event information.
165	</p>
166
167	<p>
168	<b>Note:</b>
169	The Gantt chart uses console.log() to send notifications. Press CTRL+SHIFT+J in Chrome to see the console, or use Firebug in
170	Firefox. Other browsers will vary.
