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.

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.

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).

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!

Once upon a time, at those glorious days of OS9, there was a cute little application called DataThief by Kees Huyser and Jan van der Laan. I was desperately waiting for its analytic continuation into OSX, but as many others, had to face the fact that it was discontinued. Suddenly, out of the blues, here comes this masterpiece GraphClick to fill up the vacuum. My first impression from this application is fantastic. It works beautifully,and the list of points produced is easily recognized by (say) Kaleidagraph for further treatment.

On top of everything, it is free. We can only hope this nice application will not be swallowed by a bigger company, like another succesful apllication (Curvus Pro X) by the same company (Arizona).

I would suggest however (please add it to my wish list) to control the Automatic curve detection (that is tolerance, spacing, and the total number of points) directly in the main frame, and not to hide it in the references. Furthermore, some support documentation is badly needed.
