How to display multiple images at once with matplotlib in one figure?

Question

I want to display multiple images at once in one figure (i used a set of 22 images so for the subplot i used 5 rows and 5 columns) , but the problem is they display one by one every time i close the figure, here is how i did it :

import cv2
import glob
import matplotlib.pyplot as plt



path="data/*.jpg"

images=[cv2.imread(image) for image in glob.glob(path)]
fig=plt.figure()
for i in range(len(images)):
    plt.subplot(5,5,i+1)
    plt.imshow(images[i])
    plt.show()

Perhaps you should do the final `plot.show()` outside the loop? — RufusVS, Mar 28 '22 at 16:01

The problem is you are displaying the plot within the loop, and should display it after you have placed all the images.

Move plt.show() outside the loop.

Here's how to plot multiple images with matplotlib and opencv:

import cv2
import glob
import matplotlib.pyplot as plt



path="data/*.jpg"


images=[cv2.imread(image) for image in glob.glob(path)]
fig, ax = plt.subplot(len(5))

for i in range(len(images)):
    image = plt.imread(images[i])
    ax[i].imshow(image)

plt.show()

How different is your answer compared to the first answer? I don't see any additional information here – Jeru Luke Jun 29 '22 at 20:51
@JeruLuke, not so different, but it is an alternative solution, iteratively plotting with ax[i].imshow(image) – ebenezer agbozo Jun 30 '22 at 21:05

but the OP wanted "*to display multiple images at once in one figure*" – Jeru Luke Jun 30 '22 at 21:08
