In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange. I set max_date_allowed = datetime.today().date(), but in the calendar, yesterday is the maximum date allowed. I see it in my apps, and it is also present in the first example on the DatePickerRange documentation page.

See https://github.com/biopython/biopython/blob/master/Bio/SeqFeature.py and __add__, need to do the same specifically for integer offsets.

Workaround feature + (-5) instead of feature - 5, see https://twitter.com/tomeraltman/status/1473764959347638273

In pl.pca_loagings(), there should be an option to limit the number of points plotted (basically n_points from ranking)

Why: I recently used the AnnData/scanpy suite to perform some analysis on a low number of genes (less than 30, amplified by qRT-PCR).
As the number of features is less than 30 (30 being the default value for n_points in ranking(adata,*args,**kwargs), the loadings appear twice

As reported by @jonalv , it can be confusing what is happening when if the globber pattern does not catch any files.

The suggestion is to:

• Log when the globber starts, with the pattern used
• Issue a warning if the globber doesn't match any files at all
