: 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 .

Regardless of the specific tool, the process generally follows these steps: Scalar plot digitizer - File Exchange - MATLAB Central plot-digitizer-matlab

: Detailed walkthroughs for tools like Gravit (or GRABIT) demonstrate how to load images, calibrate linear or log axes, and export data directly to the MATLAB workspace. General Digitization Workflow : For a manual, code-based approach, you can

: This tool uses an automated algorithm that can trace a graph from an initial point, picking the nearest point to the previously digitized one to speed up the process. Key Tutorials and Blog Resources General Digitization Workflow : This tool uses an

: 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.

Several powerful MATLAB-based tools and blog resources exist for digitizing (extracting data from) plots in images. The most effective approach typically involves using specialized GUI tools from the MATLAB Central File Exchange . Top MATLAB Plot Digitization Tools

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