JMulTi is an interactive software designed for univariate and multivariate time series analysis. It has a Java graphical user interface that uses an external engine for statistical computations.

JChart2D is an minimalistic charting library published under the OSI approved GNU LESSER GENERAL PUBLIC LICENSE. It is designed for displaying multiple traces consisting of tracepoints. JChart2D is centered around a single configureable swing widget: the Chart2D. It is a JComponent one can add to a java swing user interface. Therefore basic knowledge of java awt and swing and the information provided on this site is helpful. If no basic knowledge of swing and awt is given, the example code will give a quick entry as well.

The research by the information visualization community shows clearly that using a visual representation of data-sets enables faster analysis by the end users. Tulip, created by David AUBER, is a contribution of the area of information visualization, “InfoViz”. Even if the Tulip framework allows the visualization, the drawing and the edition of small graphs, all the parts of the framework have been built in order to be able to visualize graphs having more than 1.000.000 elements.
