Graph Extract

Graph Extract is a freeware program for digitizing plots. Using either manual or automated approaches this program provides a means to easily extract numeric data from plots in an intuitive manner. The resulting extracted X-Y data can be printed, replotted, or saved in either Excel (.xls) or text files for further processing. Graphs can be read as jpeg or bitmap files, scanned from hardcopy within the program, or captured and incorporated directly from the screen, e.g. from the display of a webpage or pdf file. Although completely free, this program is code signed and fully supported by Quadtech Associates.
