LilyPond Internals Reference: 3.1.14 BassFigureAlignment

### 3.1.14 `BassFigureAlignment`

An auxiliary grob to stack several `BassFigureLine` grobs vertically.

`BassFigureAlignment` objects are created by: `Figured_bass_engraver`.

Standard settings:

`axes` (list):

      '(1)

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

`padding` (dimension, in staff space):

  `-inf.0`

  Add this much extra space between objects that are next to each other.

`stacking-dir` (direction):

  `-1`

  Stack objects in which direction?

`vertical-skylines` (pair of skylines):

  `ly:axis-group-interface::calc-skylines`

  Two skylines, one above and one below this grob.

`X-extent` (pair of numbers):

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

  Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

`Y-extent` (pair of numbers):

  `#<unpure-pure-container #<procedure ly:axis-group-interface::height (_)> #<procedure ly:axis-group-interface::pure-height (_ _ _)> >`

  Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): `align-interface`, `axis-group-interface`, `bass-figure-alignment-interface`, `grob-interface` and `spanner-interface`.

This object is of class Spanner (characterized by `spanner-interface`).
