LiveGraph

LiveGraph is a framework for real-time data visualisation, analysis and logging.
A real-time plotter that can automatically update graphs of your data while it is still being computed by your application.
Concise and simple point-and-click interface that allows quickly selecting and comparing data series even in applications that output over 1000 series simultaneously.
The framework is Java-based and can run on any computer system. However, it is easily integrated with applications written in any programming language.
