106        The Line chart can be adjusted by dragging the line(s) up and down. By using the RGraph registry -
107        <i>RGraph.Registry.Get('chart.adjusting.line.myc')</i> - you can get the details of the adjustment
108        (replace <i>myc</i> with the ID of your canvas). This is an array consisting of:
109       
110        <ul>
111            <li>The chart object</li>
112            <li>The index of the point in the data series</li>
113            <li>A two element array consisting of the original coordinates of the point that is being adjusted</li>
114            <li>The index of the data series that contains the point being adjusted</li>
115        </ul>
