Answer 1

If you just want a stacked bar chart, then one way is to use a loop to plot each column in the dataframe and just keep track of the cumulative sum, which you then pass as the bottom argument of pyplot.bar

import pandas as pd
import matplotlib.pyplot as plt

# If it's not already a datetime
payout_df['payout'] = pd.to_datetime(payout_df.payout)

cumval=0
fig = plt.figure(figsize=(12,8))
for col in payout_df.columns[~payout_df.columns.isin(['payout'])]:
    plt.bar(payout_df.payout, payout_df[col], bottom=cumval, label=col)
    cumval = cumval+payout_df[col]

_ = plt.xticks(rotation=30)
_ = plt.legend(fontsize=18)
