How to use a custom png image marker in a plot (Matplotlib)?

To use custome png or jpg i.e an image as a marker in a plot, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Make a paths list to store the directories of images.
Make a list (x and y) of points.
Using subplots() method, create a figure and a set of subplots.
To plot images instead of points, iterate zipped x, y and paths.
Instantiate AnnotationBbox() with image and (x, y) points.
Put xticks and yticks on both the axes.
To display the figure, use show() method.

Example

import matplotlib.pyplot as plt
from matplotlib.offsetbox import OffsetImage, AnnotationBbox

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

def getImage(path):
   return OffsetImage(plt.imread(path, format="jpg"), zoom=.1)

paths = ['globe.jpg', 'settings.jpg', 'settings.jpg', 'globe.jpg']
x = [8, 4, 3, 6]
y = [5, 3, 4, 7]
fig, ax = plt.subplots()
for x0, y0, path in zip(x, y, paths):
   ab = AnnotationBbox(getImage(path), (x0, y0), frameon=False)
   ax.add_artist(ab)
plt.xticks(range(10))
plt.yticks(range(10))
plt.show()
