pandas 1.4.2

ParametersReturns
_create_join_index(self, index: 'Index', other_index: 'Index', indexer: 'npt.NDArray[np.intp]', how: 'str' = 'left') -> 'Index'

Parameters

index : Index being rearranged
other_index : Index used to supply values not found in index
indexer : np.ndarray[np.intp] how to rearrange index
how : str

Replacement is only necessary if indexer based on other_index.

Returns

Index

Create a join index by rearranging one index to match another

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
