EasyNData: A simple tool to extract numerical values from published plots

Understand

The comparison of numerical data with published plots is a frequently occurring task.

• In this article I present a short computer program written in Java(TM) helping in those cases where someone wants to get the numbers out of a plot but is not able to read the plot with a decent accuracy and cannot contact the author of the plot directly for whatever reason.
• The accuracy reached by this method depends on many factors.
• For the examples illustrated in this paper a precision at the level of a few per mille could be reached.
