: For a manual, code-based approach, you can use the built-in ginput function. A common workflow involves loading an image with imread , displaying it with imshow , and then using ginput to capture pixel coordinates and transform them into graph coordinates using a calibration algorithm . plot-digitizer-matlab

: One of the most popular and long-standing utilities for extracting data points from image files (BMP, JPG, TIF, GIF, and PNG). It features a GUI that allows you to calibrate axes by selecting four points and then "grab" data points by clicking along the curve. Regardless of the specific tool, the process generally

: For those looking to automate the process, Steve Eddins’ blog post Automating Data Extraction provides a deep dive into using the Image Processing Toolbox to extract data from line plots. It features a GUI that allows you to

: Specifically designed to digitize X-Y scatter plots from pictures. It is frequently updated and used for basic 2D data extraction.
