How do you directly overlay a scatter plot on top of a jpg image in Matplotlib?
To directly overlay a scatter plot on top of a jpg image, we can take the following steps −
Load an image "bird.jpg", using imread() method, Read an image from a file into an array.
Now display data as an image.
To plot scatter points on the image make lists for x_points and y_points.
Generate random numbers for x and y and append in lists.
Using scatter method, plot x and y points.
To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True data = plt.imread("logo2.jpg") im = plt.imshow(data) x_points = [] y_points = [] for i in range(10): x_points.append(np.random.randint(0, 700)) y_points.append(np.random.randint(0, 700)) plt.scatter(x_points, y_points, c=x_points) plt.show()
