__call__(self, X, alpha=None, bytes=False)

Parameters

X : float or int, ndarray or scalar

The data value(s) to convert to RGBA. For floats, X should be in the interval [0.0, 1.0] to return the RGBA values X*100 percent along the Colormap line. For integers, X should be in the interval [0, Colormap.N) to return RGBA values indexed from the Colormap with index X .

alpha : float or array-like or None

Alpha must be a scalar between 0 and 1, a sequence of such floats with shape matching X, or None.

bytes : bool

If False (default), the returned RGBA values will be floats in the interval [0, 1] otherwise they will be uint8s in the interval [0, 255] .

Returns

Tuple of RGBA values if X is scalar, otherwise an array of

RGBA values with a shape of ``X.shape + (4, )``.

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
