The "xyExtract" software is used for 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.
