pandas.io.formats.style.Styler.background_gradient

Styler.background_gradient(cmap='PuBu', low=0, high=0, axis=0, subset=None, text_color_threshold=0.408)[source]

Color the background in a gradient according to the data in each column (optionally row). Requires matplotlib.

Parameters:

cmap: str or colormap

matplotlib colormap

low, high: float

compress the range by these values.

axis: int or str

1 or ‘columns’ for columnwise, 0 or ‘index’ for rowwise

subset: IndexSlice

a valid slice for data to limit the style application to

text_color_threshold: float or int

luminance threshold for determining text color. Facilitates text visibility across varying background colors. From 0 to 1. 0 = all text is dark colored, 1 = all text is light colored.

New in version 0.24.0.

Returns:
self : Styler
Raises:

ValueError

If text_color_threshold is not a value from 0 to 1.

Notes

Set text_color_threshold or tune low and high to keep the text legible by not using the entire range of the color map. The range of the data is extended by low * (x.max() - x.min()) and high * (x.max() - x.min()) before normalizing.
