Before I start mucking around in the source code, I thought I'd try to draft a few unit tests for the behavior we'd expect for a "simple" mixture of datetime and float input to
histogramdd
.Naturally, datetime work can be a bit tricky; perhaps the most obvious issue that came up as I was drafting the unit test -- for datetime bin edges, is there an unambiguously clear "winner" in terms of a robust way to take i.e., "days" (or whatever datetime object the user provides) and "cast" it to a unit (like microseconds since the epoch) that can easily be subdivided for the various bin edge division scenarios?
