使用pandas的一个选项：

import pandas as pd

groups = {1: Group_1, 2: Group_2, 3: Group_3, 4: Group_4}

pd.DataFrame.from_dict(groups, orient='index').plot.bar(stacked=True)

输出：

变体：

(pd.DataFrame.from_dict({k: list(d.values())
                         for k, d in groups.items()},
                         orient='index')
   .plot.bar(stacked=True, legend=False)
)

输出：

一个选项使用matplotlib条形图。

import matplotlib.pyplot as plt

# Create a single structure to hold your groups. Could work with a list as well.
groups = {"1": G1.values(), "2": G2.values(), "3": G3.values(), "4": G4.values()}

for x, values in groups.items():
    bottom = 0
    for value in values:
        plt.bar(x, value, bottom=bottom)
        bottom += value
