### 3.1.14 BassFigureAlignment

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):

>   `0.2`

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

> `stacking-dir` (direction):

>   `-1`

>   Stack objects in which direction?

> `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 #<primitive-procedure ly:axis-group-interface::height> #<primitive-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.
