Hi, Now there are some ways to get histogram using polars python API, such as series.hist(). Is there an equvialent rust polars api ?

mcrumiller commented 6 months ago

The rust side has expr.hist but no series.hist.

@ritchie46 I know there is a general aversion to Series API creep but this one seems fairly useful for exploratory analysis, what do you think?

Where can I find the documentation on expr.hist ? I have searched on polars docs (https://docs.rs/polars/latest/polars/), but cannot find it.

It's also python API ?
