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.

Very easy to use, five steps:

5 Copy the data

Engineers, students, scientists, researchers, who may want to convert image curves to data
