pandas/io/formats/style.py

        with _mpl(Styler.background_gradient) as (plt, colors):
-            rng = s.max() - s.min()
+            min = s.values.min()
+            max = s.values.max()


Can you use different names for min/max so they don't override the built-in min/max functions?

sure, updated commit

@jschendel I updated the commit per your request

the failing tests/checks are not related to the change as far as I understand, is there something I should do about that?

jreback · 2018-05-31T10:09:59Z

you have linting issues:

pandas/tests/io/formats/test_style.py:1066:1: E303 too many blank lines (3)

jreback · 2018-05-31T10:10:31Z

is it worth adding the OP example here?

soxofaan · 2018-05-31T12:56:48Z

@jreback thanks, I didn't catch that linting issue warning. Lot of trees in the forest.

I think the OP example is good for interactive testing, but overkill for unit testing

soxofaan · 2018-05-31T17:28:27Z

(this PR will conflict with #21263 )

soxofaan · 2018-06-07T19:15:15Z

Had to rework this PR because #21263 has been merged

note that making background_gradient compatible with axis=None enabled to simplify the relative_luminance implementation of #21263

minor comments. lgtm.

doc/source/whatsnew/v0.24.0.txt

 - :func:`to_csv` now supports ``compression`` keyword when a file handle is passed. (:issue:`21227`)
 - :meth:`Index.droplevel` is now implemented also for flat indexes, for compatibility with MultiIndex (:issue:`21115`)
-
+- Allow elementwise coloring in ``style.background_gradient`` with ``axis=None`` (:issue:`15204`)


use :class:`pandas.io.formats.style.Styler`

or even better, I'll move it alongside with the changelog entry for PR #21263
