Corvallis, Oregon-based Rogue Wave Software Inc will preview Chart.h++, a two- and three-dimensional C++ graphics chart library at the show. It will also introduce an enhanced version of View.h++, its graphical user interface C++ class library, and launch Canvas.h++, a set of C++ structured graphics libraries. Chart.h++ supports a variety of standard charts including bar charts, histograms, scatter plots and three-dimensional surface plots. Users can add new chart types and extend existing ones as required, the firm says. The tool also supports rotation, a flexible data model and device independent colour. Rogue Wave has also revamped View.h++ adding object-oriented support for OSF/Motif 1.2 and X11.5. View.h++ now encapsulates all of the Motif interface in a C++ library, which enables developers to build graphical interface-based applications at a higher level of abstraction without directly accessing source code. It is available first for SunSoft Inc Solaris and support for HP-UX, AIX and Santa Cruz Operation Inc Unix will follow by the end of the year. A version for Microsoft Corp’s Windows NT is planned for next year. Canvas.h++, an additional module to Chart.h++, will be released next month. Rogue Wave software is distributed by Hypersoft Europe Ltd in the UK.
