Note that the x and y axis have the names we provided in the xlabel and ylabel methods of matplotlib. Note that the graph will appear in the window of your IDE if you are using P圜harm with scientific mode activated. You should see a new window like the one below with a graph of a straight line. First, copy and paste the code below in your IDE and run it. Now that you have successfully installed matplotlib, let’s jump into a simple example to give us a feel for how the library works. If you don’t have NumPy installed already, you can follow these instructions to install it for your operating system. (You can get more help from the official website if this does not work for you.) Please ensure you reference your desired Python version to avoid any surprises. Matplotlib can easily be installed on Python 2 and 3 with the following command: python -mpip install matplotlib You might be wondering, “Why not use Python’s built-in data structures?” We can’t use it for complex examples because the built-in data structures don’t have all the functions we need. In addition to matplotlib, we will be using NumPy in this tutorial. The library is capable of producing a wide range of plots however, this article will focus on generating 2D and 3D plots, as this is a common use case. Matplotlib is a graphical library for plotting mathematical functions and data in Python.
