Question

How can i create stacked bar graph from a dictionary like this

{'Chesterville': {'Bachelor': 8, 'Diploma': 5, 'Fail (Promoted)': 5, 'HC': 16},
 'Ebony Park': {'Bachelor': 1, 'Diploma': 3, 'Fail (Promoted)': 0, 'HC': 1},
 'Makhaza': {'Bachelor': 15, 'Diploma': 9, 'Fail (Promoted)': 13, 'HC': 4}}

Answer 1

You may use pandas to convert the dictionary to a DataFrame and then plot it.

import pandas as pd
import matplotlib.pyplot as plt

dic = {'Chesterville': {'Bachelor': 8, 'Diploma': 5, 'Fail (Promoted)': 5, 'HC': 16},
     'Ebony Park': {'Bachelor': 1, 'Diploma': 3, 'Fail (Promoted)': 0, 'HC': 1},
     'Makhaza': {'Bachelor': 15, 'Diploma': 9, 'Fail (Promoted)': 13, 'HC': 4}}

df = pd.DataFrame(dic)

df.plot(kind="bar", stacked=True)
plt.show()
