"""
|
||
|
|
An axis spine -- the line noting the data area boundaries.
|
||
|
|
|
||
|
|
Spines are the lines connecting the axis tick marks and noting the
|
||
|
|
boundaries of the data area. They can be placed at arbitrary
|
||
|
|
positions. See `~.Spine.set_position` for more information.
|
||
|
|
|
||
|
|
The default position is ``('outward', 0)``.
|
||
|
|
|
||
|
|
Spines are subclasses of `.Patch`, and inherit much of their behavior.
|
||
|
|
|
||
|
|
Spines draw a line, a circle, or an arc depending on if
|
||
|
|
`~.Spine.set_patch_line`, `~.Spine.set_patch_circle`, or
|
||
|
|
`~.Spine.set_patch_arc` has been called. Line-like is the default.
|
||
|
|
|
||
|
|
For examples see :ref:`spines_examples`.
