Many times you want to create a plot that uses categorical variables in Matplotlib. Matplotlib allows you to pass categorical variables directly to many plotting functions, which we demonstrate below.

import matplotlib.pyplot as plt

data = {'apples': 10, 'oranges': 15, 'lemons': 5, 'limes': 20}
names = list(data.keys())
values = list(data.values())

fig, axs = plt.subplots(1, 3, figsize=(9, 3), sharey=True)
axs[0].bar(names, values)
axs[1].scatter(names, values)
axs[2].plot(names, values)
fig.suptitle('Categorical Plotting')
