df.plot(..., kind="hist").

Goal

Draw this kind four ways.

df = pd.DataFrame({
    "city": ["Nairobi", "Mombasa", "Kisumu", "Nakuru", "Eldoret"],
    "units": [21, 15, 15, 18, 12],
    "shillings": [2100, 1500, 1480, 1750, 1190],
})
df.plot(y="units", kind="hist")
plt.title("hist")
plt.show()

rng = np.random.default_rng(0)
s = pd.Series(rng.integers(1, 20, size=80), name="units")
s.plot(kind="hist", bins=8)
plt.title("hist")
plt.show()

df = pd.DataFrame({
    "city": ["Nairobi", "Mombasa", "Kisumu", "Nakuru", "Eldoret"],
    "units": [21, 15, 15, 18, 12],
    "shillings": [2100, 1500, 1480, 1750, 1190],
})
print(df.head())
df.plot(x="city", y="shillings", kind="hist")
plt.show()
