Description:

GraphClick is a graph digitizer software which allows to automatically retrieve the original (x,y)-data from the image of a scanned graph or from a QuickTime movie. It features:
- Automatic detection of curves (solid, dotted or dashed), symbols, bar charts, or perimeters of areas
- Almost all file formats recognized (PDF, JPEG, GIF, TIFF, Photoshop, etc.)
- Frame-by-frame digitization of QuickTime movies
- Image modification for adjustment (edge detection, blur, sharpen, etc.)
- Can handle arbitrarily deformed axis systems, and two ordinate axes
- Linear, logarithmic or inverse scales
- Error bars
- Several data set in the same document
- Unlimited undo

Note: there are some incompabilitities with Retina display. For better results, make sure GraphClick opens in non-Retina mode. In the Finder, select GraphClick and choose File > Get Info. Check the button "Open in Low Resolution". A fix is will be provided shortly.

Review by Mac Rulez

Works great - Bought this app recently. Works wonderful! Very user-friendly, they have online tours in case confused of what and how to use; Help includes all the information you could ever ask for. I was using datathief earlier which only complicated things, this thing is a real savior. I wonder why there aren't many reviews. Possibly only downside is that there hasn't been updates since a long time (but frankly that doesn't matter as long as it works the way it is right now) and am afraid if they kill it sometime down the lane (ProVoc. a product from Arizona too was killed and is no longer available).

Best data-extraction software I tested so far - I have to extract data points from scanned plots or PDF reasonably often. Graphclick is the best program that I tested so far in this respect! Very easy to setup the axes, extract the data and export it as ASCII files.

CAUTION! False data possible- 10.9 broken - Please use caution when using this software. The below was my experience. Be aware that the data from auto-find functionality and masking is fake and is no longer working properly. I almost published incorrect data because of this bad bug. I’m on a 15” retina MBP, using latest system os (10.9). Software devs appear to be ignoring all needed bug fixes. In Mountainlion I was apparently bitten by some sort of masking bug- auto-selection of lines within a graph worked on a scaled-up and off-set version of the graph in memory somehow. Not sure how the bug happened- but it apparently even bit Keynote from Apple (they fixed it in 10.9). Unfortunately it appears new bugs have arisen in Mavericks, and crashes occur fairly frequently, so I cannot test if the mask/autodetect bug has been fixed. Under snow leopard this program was fantastic. Since then I don’t think much has been working, unfortunately. [Point detection degraded to the mid-point of painted masks essentially, meaning no auto selection was occuring.] I hope that the program can be fixed, as I used to use it constantly.

Excellent application, easy to get what I need from it - I have been using this program for about 6 - 7 months now and continue to like it a lot. I especially like the ability to acquire data points/curves from plots with logarithmic axes, because most of the plots I digitize with it have log axes. The demo videos on the website are good, too, demonstrating enough so that once I poked around a bit and pushed all the buttons I could pretty easily figure out what it could do. I will continue to use it.

Review by ebitnet

Far better than DataThief - I usually use DataThief (which is free) for taking experimental data from papers for comparison against some of my theoretical work. In some cases, the raw data I need is simply not available or is embedded in an image of some sort as opposed to xy data points. For less than the price of a good beer or cup of coffee, this program is a bargain! It's far superior to DataThief. It exports the data in a logical way, allows for non-linear or distorted scales, and is really easy to use.
