Short Answer 
To install Matplotlib in Visual Studio Code, first select your Python interpreter using the Command Palette (Ctrl+Shift+P). Then, open the terminal (Ctrl+`) and run the command ‘pip install matplotlib’ to complete the installation and enable you to use the library in your projects.
Step 1: Open Command Palette and Select Interpreter
Start by launching Visual Studio Code (VS Code) and ensure that the Python extension is installed. To select your desired Python interpreter, open the Command Palette by pressing Ctrl+Shift+P (Windows/Linux) or CMD+Shift+P (macOS). Look for the option ‘Python: Select Interpreter’ and choose from the list of available interpreters to set it as your environment.
Step 2: Open Terminal in VS Code
After selecting your Python interpreter, you need to access the terminal to run the installation command. You can do this by either navigating to the ‘View’ menu and choosing ‘Terminal’ or using the shortcut Ctrl+` (backtick key). This terminal will allow you to execute Python commands directly within your VS Code environment.
Step 3: Install Matplotlib
With the terminal open, you can install Matplotlib, a powerful library for visualizations in Python. In the terminal, type ‘pip install matplotlib’ and press Enter to execute the command. Once the installation is complete, you can easily import Matplotlib in your scripts using import matplotlib.pyplot as plt, allowing you to create various charts and graphs.
