# plotOptions.series.dataLabels.alignTo

Alignment method for data labels. If set to `plotEdges`, the labels are aligned within the plot area in the direction of the y-axis. So in a regular column chart, the labels are aligned vertically according to the `verticalAlign` setting. In a bar chart, which is inverted, the labels are aligned horizontally according to the `align` setting. Applies to cartesian series only.
