This article mainly introduces what is the use of Matplotlib in Python. It is very detailed and has a certain reference value. Interested friends must finish reading it!

Preface

Matplotlib is the most popular drawing library in Python, which is mainly used for 2D drawing and 3D drawing.

1. Installation of Matplotlib

You can install it by executing the following statement in cmd:

Pip install matplotlib

If you are using an integrated development environment, such as pycharm, it comes with it and can be used directly.

2. Testing

Matplotlib.pyplot is a collection of command-style functions that can be drawn by calling related functions, such as the simplest one, as shown below:

The above three lines of code complete the drawing of a simple line chart. Where the range of the x-axis is 1: 4 and the range of the y-axis is 100: 460.

The code is copied as follows:

Import matplotlib.pyplot as pltplt.plot ([1,2,3,4], [100,250,300,460]) plt.show ()

On the first line, introduce the matplotlib.pyplot package and simplify it to plt. It's an agreement, and almost everyone does it.

On the second line, call plt's function plot to draw the graph, which determines whether it is a straight line or a broken line according to the parameters in ().

The third line calls the show () function to display the graph.

Among them, the plot () function takes many parameters, including x-axis range, y-axis range, legend, coordinate axis, title, and so on.
