Data Analysis Applications for MacOSX
A few years ago Scott Hannahs compiled a fabulous list of the tools for Data Analysis available for Mac OS X for the SciTech mailing list and I thought it would be useful to spread the word, since then many people have contacted me and the list has grown. Remember that many of the more expensive applications have free/cheap education or student versions. Updated 14 Nov 2011.

Whilst the tools above provide a wealth of alternatives for exploring and analysing data one other request often comes up, if you have a hard copy of a graph how do you get the data into one of the above packages. I know of two tools that help in this task.
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 is a native Mac OS X application and an Apple design award winner.
DataThief III is a Java application to extract (reverse engineer) data points from a graph. Typically, you scan a graph from a publication, load it into DataThief, and save the resulting coordinates, so you can use them in calculations or graphs that include your own data.
