Matplotlib Plot Image Overlay is a powerful technique for visualizing data on images. We’ll explore how to accurately overlay plots onto images using Matplotlib, addressing common alignment challenges and leveraging advanced techniques for enhanced visualization.

Aug 14, 2024 · This tutorial will demonstrate how to create a grid of images using Matplotlib's ImageGrid. We will create a 2x2 grid of images and explore various ways to add colorbars to the grid.

Align multiple images using ImageGrid. import matplotlib.pyplot as plt import numpy as np from mpl_toolkits.axes_grid1 import ImageGrid im1 = np . arange ( 100 ) . reshape (( 10 , 10 )) im2 = im1 . T im3 = np . flipud ( im1 ) im4 = np . fliplr ( im2 ) fig = plt . figure ( figsize = ( 4. , 4.

In this tutorial, we learned how to create a grid of images using Matplotlib's ImageGrid. We explored different ways to add colorbars to the grid, including using a single colorbar for all images, giving each image its own colorbar, and giving each image its own colorbar with a different colorbar range.
