Plot-digitizer-matlab -

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

: A modern app that handles various image formats and supports complex digitizations, including log-scaled, tilted, skewed, or polar plots. It can re-interpolate data to a specified sampling rate, which is useful for further analysis like surface interpolation. 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 : Specifically designed to digitize X-Y scatter plots

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 It can re-interpolate data to a specified sampling

: 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.
