Скачать или смотреть Matplotlib Graphic Plotting Tutorial with Python - [ Pyplot Plotting ] - 5/13

In this lesson you will learn about Markers! Now you can punctuate or mark in different formats instead of drawing. For instance

import matplotlib.pyplot as plt
import numpy as np

x = np.array([0, 1, 2, 3])
y = np.array([3 ,1 , 2, 7])


plt.plot(x, y, marker="o")

Here we put a third parameter, the marker.
By the way, x and y are permanent parameters, they have to be there all the time, sometimes you can just use x and sometimes just y. Because if x is not present, the system automatically defaults to it, for example, when y = [ 3, 1, 4, 7], x automatically defaults to x = [0, 1, 2, 3]

As we said, if you do marker="o", the line will disappear! and only two o-points will remain.

The default line pattern is marker=''--" so you can change these drawings.
