/**
* Class: $.jqplot.PointLabels
* Plugin for putting labels at the data points.
*
* To use this plugin, include the js
* file in your source:
*
* >
*
* By default, the last value in the data ponit array in the data series is used
* for the label. For most series renderers, extra data can be added to the
* data point arrays and the last value will be used as the label.
*
* For instance,
* this series:
*
* > [[1,4], [3,5], [7,2]]
*
* Would, by default, use the y values in the labels.
* Extra data can be added to the series like so:
*
* > [[1,4,'mid'], [3 5,'hi'], [7,2,'low']]
*
* And now the point labels would be 'mid', 'low', and 'hi'.
*
* Options to the point labels and a custom labels array can be passed into the
* "pointLabels" option on the series option like so:
*
* > series:[{pointLabels:{
* > labels:['mid', 'hi', 'low'],
* > location:'se',
* > ypadding: 12
* > }
* > }]
*
* A custom labels array in the options takes precendence over any labels
* in the series data. If you have a custom labels array in the options,
* but still want to use values from the series array as labels, set the
* "labelsFromSeries" option to true.
*
* By default, html entities (<, >, etc.) are escaped in point labels.
* If you want to include actual html markup in the labels,
* set the "escapeHTML" option to false.
*
