asfreq(self, freq=None, how: 'str' = 'E') -> 'PeriodIndex'
Equivalent to applying pandas.Period.asfreq
with the given arguments to each ~pandas.Period
in this PeriodArray.
A frequency.
Whether the elements should be aligned to the end or start within pa period.
'E', 'END', or 'FINISH' for end,
'S', 'START', or 'BEGIN' for start.
January 31st ('END') vs. January 1st ('START') for example.
The transformed PeriodArray with the new frequency.
Convert the PeriodArray to the specified frequency :None:None:`freq`.
Period.asfreq
Convert a :None:class:`~pandas.Period` object to the given frequency.
pandas.arrays.PeriodArray.asfreq
Convert each Period in a PeriodArray to the given frequency.

pandas.core.arrays.period.PeriodArray.asfreq
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
