xyscan is a tool for scientist in the need to extract data points, i.e. numeric values, from a plot. It allows to scan the plots and extract data points including the size of the error bars (both in x and y). It can handle plots with linear and logarithmic scales. In fact xyscan can be used for extracting numeric values from any kind of 2D technical drawings. Click here for a screen shot of xyscan in action.

Latest News:
Version 3.3.3 is ready (July 2014). This is a Mac OSX binary and source code only release. xyscan finally moved to Qt5 and is now handling Retina screens properly. The French documentation was updated by Boris Hippolyte (thanks Boris). Otherwise minor changes only. This version is not tested on Linux and Windows but should be easy to build from the source code.

Supported Platforms

xyscan is currently supported only on MAC OS X. It will most certainly run on the different Linux flavors and recent Windows versions but I have no time to test any of these platforms right now. I am very grateful that others stepped in and there is now a distributions available for Gentoo. See also the pages at the Fink web site. Many thanks to all that helped maintaining and distributing it.

Special thanks to Seth Vidal from Duke University who helped me building the first rpm for Linux (xyscan version 2) and who introduced me to the world of licensing and GPL. Many thanks to Valeri Fine who came up with the double-click improvement in 3.1.0. I am very grateful to Benjamin Bannier who made the Gentoo port possible. Last but not least I want to thank Jd Bourlier big time. Without him there would be no French version. Boris Hippolyte is now helping me keeping the French version up to date.
