# yAxis.labels.reserveSpace

Whether to reserve space for the labels. By default, space is reserved for the labels in these cases:

- On all horizontal axes.
- On vertical axes if `label.align` is `right` on a left-side axis or `left` on a right-side axis.
- On vertical axes if `label.align` is `center`.

This can be turned off when for example the labels are rendered inside the plot area instead of outside.
