matplotlib.patches.FancyArrow

classmatplotlib.patches.FancyArrow(x, y, dx, dy, width=0.001, length_includes_head=False, head_width=None, head_length=None, shape='full', overhang=0, head_starts_at_zero=False, **kwargs)[source]

Bases: matplotlib.patches.Polygon

Like Arrow, but lets you set head width and head height independently.

Parameters

x, yfloat

The x and y coordinates of the arrow base.

dx, dyfloat

The length of the arrow along x and y direction.

widthfloat, default: 0.001

Width of full arrow tail.

length_includes_headbool, default: False

True if head is to be counted in calculating the length.

head_widthfloat or None, default: 3*width

Total width of the full arrow head.

head_lengthfloat 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.

overhangfloat, default: 0

Fraction that the arrow is swept back (0 overhang means triangular shape). Can be negative or greater than one.

head_starts_at_zerobool, default: False

If True, the head starts being drawn at coordinate 0 instead of ending at coordinate 0.

head_width: float or None, default: None

Total width of the full arrow head.

head_length: float or None, default: None

Length of arrow head.
