### 3.1.125 VerticalAxisGroup

VerticalAxisGroup objects are created by: Axis_group_engraver and Hara_kiri_engraver.

Standard settings:

> `axes` (list):

>   `'(1)`

>   List of axis numbers. In the case of alignment grobs, this should contain only one number.

> `Y-offset` (number):

>   `ly:hara-kiri-group-spanner::force-hara-kiri-callback`

>   The vertical amount that this object is moved relative to its Y-parent.

> `Y-extent` (pair of numbers):

>   `ly:hara-kiri-group-spanner::y-extent`

>   Hard coded extent in Y direction.

> `X-extent` (pair of numbers):

>   `ly:axis-group-interface::width`

>   Hard coded extent in X direction.

> `vertical-skylines` (unknown):

>   `ly:hara-kiri-group-spanner::calc-skylines`

>   Two skylines, one above and one below this grob.

> `max-stretch` (number):

>   `ly:axis-group-interface::calc-max-stretch`

>   The maximum amount that this `VerticalAxisGroup` can be vertically stretched (for example, in order to better fill a page).

> `stencil` (unknown):

>   `ly:axis-group-interface::print`

>   The symbol to print.
