Horizontal stacked bar chart in Matplotlib

To plot stacked bar chart in Matplotlib, we can use barh() methods

Steps

Set the figure size and adjust the padding between and around the subplots.
Create a list of years, issues_addressed and issues_pending, in accordance with years.
Plot horizontal bars with years and issues_addressed data.
To make stacked horizontal bars, use barh() method with years, issues_pending and issues_addressed data
Place the legend on the plot.
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

year = [2014, 2015, 2016, 2017, 2018, 2019]
issues_addressed = [10, 14, 0, 10, 15, 15]
issues_pending = [5, 10, 50, 2, 0, 10]

b1 = plt.barh(year, issues_addressed, color="red")

b2 = plt.barh(year, issues_pending, left=issues_addressed, color="yellow")

plt.legend([b1, b2], ["Completed", "Pending"], title="Issues", loc="upper right")

plt.show()
