AptPlot - A Free Pure-Java 2D Plotting Tool
AptPlot is a WYSIWYG 2D plotting tool designed for creating production quality plots of numerical data and performing data analysis. AptPlot contains extensive scripting and GUI support for the manipulation and analysis of data sets. AptPlot is intended to be a pure-Java drop-in replacement for the the Motif X-Window based Grace plotting package maintained by the Grace Team and coordinated by Evgeny Stambulchik.
Although Grace has provided extensive capability for plotting and data analysis tools for several years it is also host to several limitations, primarily associated with execution under Microsoft Windows. It is written as an X-Windows Motif application in a combination of C, LEX, YACC, and IDL coding. The software is specifically tailored for Unix machines; users working with operating systems that do not provide Unix-like functionality often found installing and maintaining Grace difficult. With this in mind, APT has developed AptPlot as a functional clone of Grace using the Java programming language.
In addition to vastly improved portability, authoring the tool in Java eases the addition of a host of other improvements, such as a plug-in interface which allows the application to be extended in any number of ways at runtime. The NRC Analysis Code specific features inherent in AcGrace (formerly Xmgr5) have been extracted into a separate plug-in.
