CLN: Exception in pd.plotting
> Do these Exceptions ever surface? And if so, do we have any coverage on these?

With the exception of the "pragma: no cover" on 433, these code paths are all reached in the tests.

#28347 adds a check for `except:`.  Checking for `Exception` is harder because there are some cases where we can't make it any more specific.

Most of the remaining cases are in apply/groupby/resample and are pretty nasty.  I wouldn't recommend then for a newcomer. Closing to clear the queue since large parts of this have unclear desired behavior.  Before long I'll revisit to address only obvious pieces.
