matplotlib 3.5.1

Parameters
__init__(self, 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)

Parameters

x, y : float

The x and y coordinates of the arrow base.

dx, dy : float

The length of the arrow along x and y direction.

width : float, default: 0.001

Width of full arrow tail.

length_includes_head : bool, 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 : bool, default: False

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

**kwargs :

.Patch properties:

Properties: agg_filter: a filter function, which takes a (m, n, 3) float array and a dpi value, and returns a (m, n, 3) array alpha: unknown animated: bool antialiased or aa: bool or None capstyle: .CapStyle or {'butt', 'projecting', 'round'} clip_box: .Bbox clip_on: bool clip_path: Patch or (Path, Transform) or None color: color edgecolor or ec: color or None facecolor or fc: color or None figure: .Figure fill: bool gid: str hatch: {'/', '\\', '|', '-', '+', 'x', 'o', 'O', '.', '*'} in_layout: bool joinstyle: .JoinStyle or {'miter', 'round', 'bevel'} label: object linestyle or ls: {'-', '--', '-.', ':', '', (offset, on-off-seq), ...} linewidth or lw: float or None path_effects: .AbstractPathEffect picker: None or bool or float or callable rasterized: bool sketch_params: (scale: float, length: float, randomness: float) snap: bool or None transform: .Transform url: str visible: bool zorder: float

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
