How to plot a dataframe

In this post, I will teach you how to plot a dataframe you created in Pandas.

This is my sample dataframe whose graph I would like to draw.

import pandas as pd

my_data = {'Tax_Rate': [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7],
           'Taxes_Collected': [100000000, 120000000, 170000000, 260000000, 210000000, 80000000, 40000000]}

my_df = pd.DataFrame(my_data)

I wanted to represent the Laffer curve, so I chose lines and bars.

To plot the chart I will use the matplotlib module which I need to import.

import pandas as pd
import matplotlib.pyplot as plt

my_data = {'Tax_Rate': [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7],
           'Taxes_Collected': [100000000, 120000000, 170000000, 260000000, 210000000, 80000000, 40000000]}

my_df = pd.DataFrame(my_data)

my_df.plot.bar(x='Tax_Rate', y='Taxes_Collected')
plt.plot(my_df)

plt.show()

This is the simplest plot you can create from a dataframe using matplotlib. The matplotlib module also allows you to expand the plot further to suit your needs.
