Digitizing data from old figures with ImageJ

Digitizing data from old figures with ImageJ

 

Following on this earlier post concerning the retrieval of data from figures in published papers with R, here is a method for doing the same with ImageJ. This is a freely available program that should run on Windows/Mac/Linux, just like R. To extract data points from a figure, you’ll need the Figure_Calibration plugin developed by Frederic V. Hessman, available here. Download the Figure_Calibration.class file from that page and save it to your ImageJ/plugins/ directory. Then load up ImageJ.
