: Specifically designed to digitize X-Y scatter plots from pictures. It is frequently updated and used for basic 2D data extraction.
Regardless of the specific tool, the process generally follows these steps: Scalar plot digitizer - File Exchange - MATLAB Central plot-digitizer-matlab
: 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 : Specifically designed to digitize X-Y scatter plots
: 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. Key Tutorials and Blog Resources : One of
