arrow
(x, y, dx, dy, **kwargs)¶ Add an arrow to the axes.
Call signature:
arrow(x, y, dx, dy, **kwargs)
Draws arrow on specified axis from (x, y) to (x + dx, y + dy). Uses FancyArrow patch to construct the arrow.
The resulting arrow is affected by the axes aspect ratio and limits. This may produce an arrow whose head is not square with its stem. To create an arrow whose head is square with its stem, use
annotate()
.Optional kwargs control the arrow construction and properties:
- Constructor arguments
- width: float (default: 0.001)
- width of full arrow tail
- length_includes_head: [True | False] (default: False)
- True if head is to be counted in calculating the length.
- head_width: float or None (default: 3*width)
- total width of the full arrow head
- head_length: float or None (default: 1.5 * head_width)
- length of arrow head
- shape: [‘full’, ‘left’, ‘right’] (default: ‘full’)
- draw the left-half, right-half, or full arrow
- overhang: float (default: 0)
- fraction that the arrow is swept back (0 overhang means triangular shape). Can be negative or greater than one.
- head_starts_at_zero: [True | False] (default: False)
- if True, the head starts being drawn at coordinate 0 instead of ending at coordinate 0.
- Other valid kwargs (inherited from

) are: - agg_filter: unknown
alpha: float or None
animated: [True | False]
