# series.xrange.dataLabels

Options for the series data labels, appearing next to each data point.

Since v6.2.0, multiple data labels can be applied to each single point by defining them as an array of configs.

In styled mode, the data labels can be styled with the `.highcharts-data-label-box` and `.highcharts-data-label` class names (see example).
