Dec 21, 2020 · You can zoom the image and the set the box alignment to the lower right corner (0,1) plus some extra for the margins: im = OffsetImage(arr_img, zoom=.45) ab = AnnotationBbox(im, (1, 0), xycoords='axes fraction', box_alignment=(1.1,-0.1))

This post explains how to insert an image into your matplotlib plot using the PIL and io libraries. Two use cases are considered: your image beeing stored locally or somewhere on the web. Adding a logo to your matplotlib graphics can be a bit tricky when you've never done it before.

Many ways to plot images# The most common way to plot images in Matplotlib is with imshow. The following examples demonstrate much of the functionality of imshow and the many images you can create.

Dec 25, 2015 · I would like to plot a graph over an image background using matplotlib. I found how to do it in matlab http://www.peteryu.ca/tutorials/matlab/plot_over_image_background. I've tried something basic like this:

Jan 5, 2020 · Loading image data is supported by the Pillow library. Natively, Matplotlib only supports PNG images. The commands shown below fall back on Pillow if the native read fails. The image used in this example is a PNG file, but keep that Pillow requirement in mind for your own data. Here's the image we're going to play with:

Nov 23, 2024 · Matplotlib.pyplot.figimage () function in Python is a powerful tool for adding images directly to the figure canvas in Matplotlib. This function allows you to place images on the figure without using an axes object, providing flexibility in image placement and manipulation.
