A free image curve extract tool that is simple and easy to use
Coverting scanned graphs to data, that is, extracting (x,y) data from scanned graphs can be useful for analyzing data from published graphs, analog instruments, strip chart recordings, or any other hard copy graph or plot. This is sometimes called a "plot digitizer", "graph digitizer", or "optical plot reading" (OPR)
Very easy to use, five steps:
1 Capture curve from screen - A first example
2 Calibration
3 Erase to make curve isolated
4 Choose curve by connectivity, color, dragging a rectangle, points
5 Copy the data
Engineers, students, scientists, researchers, who may want to convert image curves to data

ok. Lot's of improvements needed before became usefull.
I have tried a log-log curve and the software has no capability to understand that. Otherwise, it is ok. More

Good and easy to use..
Really easy to use, in 5 mim I managed to digitize a curve and export to an Excel spreadsheet.
I am adding a link to this excellent tool on my engineering website (Engineers' Tool Kit)and will spread the info to my groups.
Thank you for making this tool available and free.
