To plot a histogram for discrete values with matplotlib, we can use hist() method.
Steps
Set the figure size and adjust the padding between and around the subplots.
Make a list of discrete values.
Use hist() method to plot data with bins=length of data and edgecolor=black.
To display the figure, use show() method.
Example
from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True data = [1, 4, 2, 3, 5, 9, 6, 7] plt.hist(data, bins=len(data), edgecolor='black') plt.show()
