matplotlib 3.5.1

ParametersReturnsBackRef
to_rgba_array(c, alpha=None)

Parameters

c : Matplotlib color or array of colors

If c is a masked array, an ndarray is returned with a (0, 0, 0, 0) row for each masked value or row in c.

alpha : float or sequence of floats, optional

If alpha is given, force the alpha value of the returned RGBA tuple to alpha.

If None, the alpha value from c is used. If c does not have an alpha channel, then alpha defaults to 1.

alpha is ignored for the color value "none" (case-insensitive), which always maps to (0, 0, 0, 0) .

If alpha is a sequence and c is a single color, c will be repeated to match the length of alpha.

Returns

array

(n, 4) array of RGBA colors, where each channel (red, green, blue, alpha) can assume values between 0 and 1.

Convert c to a (n, 4) array of RGBA colors.

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
