I want to extract data points from a scanned graph. But all software I found was not for free.
The very simple but completely free program is this one: http://www.star.bnl.gov/public/comp/vis/Thomas/xyscanDistributionPage/ . There were some others with more complicated functionality, but I do not remember their names.
I have a rock specimen and a soil specimen. During my mechanical measurements I observed that the rock reacts much faster on stress rate changes (observable by a sharp kink in the deformation...
