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.
