pandas style background gradient both rows and columns

Currently you can't set the background_gradient for both the rows/columns simultaneously as pointed by Nickil Maveli. The trick is to customize the pandas function background_gradient:

import pandas as pd
import matplotlib.pyplot as plt
from matplotlib import colors

def background_gradient(s, m, M, cmap='PuBu', low=0, high=0):
    rng = M - m
    norm = colors.Normalize(m - (rng * low),
                            M + (rng * high))
    normed = norm(s.values)
    c = [colors.rgb2hex(x) for x in plt.cm.get_cmap(cmap)(normed)]
    return ['background-color: %s' % color for color in c]

df = pd.DataFrame([[3,2,10,4],[20,1,3,2],[5,4,6,1]])
df.style.apply(background_gradient,
               cmap='PuBu',
               m=df.min().min(),
               M=df.max().max(),
               low=0,
               high=0.2)

You need to set axis to None. For me best solution using seaborn:

import seaborn as sns
import pandas as pd
cm = sns.color_palette("blend:white,green", as_cmap=True)
df.style.background_gradient(cmap = cm,axis=None)

Setting axis=None is working for me in 1.0.5

You can use axis=None to get rid of the min and max computations in the call:

def background_gradient(s, m=None, M=None, cmap='PuBu', low=0, high=0):
    print(s.shape)
    if m is None:
        m = s.min().min()
    if M is None:
        M = s.max().max()
    rng = M - m
    norm = colors.Normalize(m - (rng * low),
                            M + (rng * high))
    normed = s.apply(norm)

    cm = plt.cm.get_cmap(cmap)
    c = normed.applymap(lambda x: colors.rgb2hex(cm(x)))
    ret = c.applymap(lambda x: 'background-color: %s' % x)
    return ret


df.style.apply(background_gradient, axis=None)

Edit: You may need to use normed = s.apply(lambda x: norm(x.values)) for this to work on matplotlib 2.2
