103        The Radar chart can be adjusted by dragging the points on the chart. When the <i>onadjustend</i> event fires, you will find
104        the following information in the RGraph registry - <i>RGraph.Registry.Get('chart.adjusting.radar.myc')</i> - where <i>myc</i>
105        is the ID of your canvas:

110        <li>The numerical, zero indexed point that relates to the original data array</li>
111        <li>This is a boolean and used to indicate which (horizontal) half of the chart the point is in. true - the right half, false - the left half</li>
