This is a side-effect of porting the method from Expr to Series.
For Expr, the resulting expression is named "a"
in all cases, but when include_breakpoint=True
the return data type is a Struct and the fields are named breakpoint/count. Because we expand that struct to a dataframe in the Series method, the original name is lost.
I think the best solution would be to just follow Expr here and return a Struct Series, not a DataFrame. That's how cut/qcut
work at the moment. What would you think of that solution?
hist
is sort-of modeled after cut/qcut
, but we aim to overhaul that API so that is not very helpful either.

Returning a struct series seems fine to me.
