# series.columnrange.dataLabels.overflow

How to handle data labels that flow outside the plot area. The default is `"justify"`, which aligns them inside the plot area. For columns and bars, this means it will be moved inside the bar. To display data labels outside the plot area, set `crop` to `false` and `overflow` to `"allow"`.
