Retrieve data from a graph image.

Overview

GraphClick is a graph digitizer software which allows to automatically retrieve the original (x,y)-data from a scanned graph, a chart or a movie.

You have the picture of a graph but not the corresponding data? GraphClick is then simply the best way to solve the problem! You just have to click on the graph, and the obtained coordinates of the points can be directly exported into any other application. The idea is very simple, but its usefulness is likely to become essential.

  • Automatic dectection of curves (solid, dotted or dashed), symbols, bar charts or perimeters of areas
  • Linear, logarithmic or inverse scales
  • Error bars
  • Most image formats recognized (GIF, TIFF, Photoshop, PDF, etc.)
  • Frame-by-frame digitization of QuickTime movies
  • Image modification for adjustment (edge detection, blur, sharpen, etc.)
  • Can handle arbitrarily deformed images, and two ordinate axes
  • Several data set in the same document
  • Unlimited undo
  • And much more

What's new in GraphClick

Version 3.0:
  • Map projections (Mercator, oblique Mercator, transverse Mercator, gnomonic)
  • Data sets can now be copied as columns (i.e. side by side)
  • Keep coordinates or positions of data points during copy/paste
  • Various minor bugs fixed

This is just an amazing little piece of software, I thought the only way to go with this thing was datathief, which is an ugly, slow, buggy, expensive piece of software, but then I stumbled upon GraphClick. If you need to take data from plots, go for it. The only minus is that it doesn't state clearly the limitations of the shareware version, so when you find them out, you have to buy it, because it is extremely well done.

3.0.2 purchased MAS - bug exists It appears that the program cannot select data properly on my macbookpro retina running 10.8.2. I'm trying to data-mine a black and white decent resolution graph from a journal article, and currently the system is no-go. Selecting data in the white of the image, not on the data-line. Using masks only ends up with data that is at the center of the mask (ignores actual line of data). Upon closing the document I noticed a weird version of the image in the window flash for a few seconds. I suspect the view of the image is different than the image being mined, and you're lucky if you happen to click on the proper portion of the image that the software has in it's head -v- what you can see. Contacted developer, we'll see what the situation is. May have to request a return of the software from apple. BTW, I often suggested this software to my co-workers in the past, so previous versions had been working as far as I can tell. Current versions having difficulty.

Agree. Good to know the app is still alive. It hasn't been updated for 4 years now and I was already thinking that it might have become abandonware.

Nice program with good features BUT purchasing a new license sends emails, but the license codes don't work, at least not on a 64 bit system running Lion.

I can't figure out how to revise this rating. But developer is very responsive and fixed the licensing issue pronto. So I would have to raise my rating.

Limitation is exporting only 10 data points.

No update for over a year. The other developers apps have either been sold on (PhotoPresenter) or discontinued (the excellent and unmatched ProVoc, which is sorely missed). I am therefore hesitant to pay $8 for this app. Granted, it is a nice piece of software. But I only support shareware that is in active development. And I do not get the feeling that Arizona Software is still around.

Graphclick is one my favorite Mac apps. It is as valuable to me as some very expensive apps like Labview, Igor Pro and the MS office suite. It's a bit surprising it doesn't have more reviews, but the reason might be that this app is the one to reach for at the start of a data crunching project that gets forgotten by the end, because it performed its task so well. I think I've been using this for 3 years or more. Every now and then a startup message informs that an update is available. I haven't run into any problems that required an update to fix, but I install them anyway and continue to have trouble-free performance.

In the middle of a really difficult late-night review of some of my predecessors work, I needed to convert some graphical data back into "real" numbers. After much shopping around, I ran across GraphClick, and it saved my bacon. The $8 shareware fee completely belies how useful and well-written this program is.

Note that help files do not correspond to 2.4b1 version - keyboard shortcuts are not the same; axis deformation tool doesn't seem to work properly (although I may not be using it correctly because Help is not up to date yet).

I use both. Digitizer on a PC at work and Graphclick at home. Engauge Digitizer might be free... But that's the only advantage. It's no real competitor to Graphclick!! Graphclick works like a charm, is easy to use AND has a REAL Mac OS X UI!!! Digitizer is quite strange to use and has a QT UI... d:-((( I'd wish, there would be kind of a Graphclick version for PC...

It is a pleasure to see how GraphClick is becoming more and more professional. It is definitely one of the coolest, as well as useful, scientific applications around. I will pay the $8 gladly; I think it worth much more... In a more 'mathematical' language, 2.2 -2.1 >> $8. One must also appreciate the fact that the developer takes very seriously the feedback comments made by MacUpdate reviewers. All items in my wish list, for example, have been fully and elegantly incorporated. Highly recommended!
