The "xyExtract" software is used to extract data from a 2D graph (orthogonal and nonorthogonal axes) contained in a graphic file (scanned, PDF document or in a some file like gif, jpg, etc). The graphic file must be saved in a bitmap file. Then, the "xyExtract" converts the graph back to xy data file (up to 1500 points). If you want, use the ?Save Project? option on the ?File? menu, for a posterior opening of the work. After each click, use the ?Adjustment? option to move the marked point (pixel to pixel), if necessary. Important: the xyExtract is a easy-to-use software and it guides you during whole the process for the points recovery.
