: 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

: 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

: Specifically designed to digitize X-Y scatter plots from pictures. It is frequently updated and used for basic 2D data extraction. A common workflow involves loading an image with

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
