An internet search turns up quite a few options. I haven't used any of these; I can't speak to their quality or whether they will fit your needs, but here are a few links: http://plotdigitizer.sourceforge.net/ http://www.datathief.org/ http://www.getdata-graph-digitizer.com/ http://www.digitizeit.de/ You might also look in the "External links" section of this Wikipedia article http://en.wikipedia.org/wiki/Converting_scanned_graphs_to_data ________________________________________ From: owner-statalist@hsphsun2.harvard.edu [owner-statalist@hsphsun2.harvard.edu] On Behalf Of Laplante, Benoît [Benoit.Laplante@ucs.inrs.ca] Sent: Thursday, May 31, 2012 1:17 PM To: statalist@hsphsun2.harvard.edu Subject: st: Printed figure to coordinates Hi, I have a figure representing four survival curves printed in 1942 and based on census data. I do not have the corresponding table. I have no access to the original data. I need to compare the underlying hazard curves to curves estimated from recent data. Does anyone know of a piece of optical recognition software that can recognize curves and compute coordinates? Thanks in advance.
