S-PLUS is based on the latest version of the powerful, object-oriented S language originally developed at Lucent Technologies. S is a rich environment designed for interactive data discovery and is the only language created specifically for data visualization and exploration, statistical modeling, and programming with data. S-PLUS continues to be the premier solution for your data analysis and technical graphing needs. The Microsoft Office-compatible user interface gives you point-and-click access to data manipulation, graphing, and statistics. With S-PLUS, you can program interactively using the S-PLUS programming language. In a typical S-PLUS session, you can: • Import data from virtually any source. • View and edit your data in a convenient Data window. • Create plots with the click of a button. • Control every detail of your graphics and produce stunning, professional-looking output for export to your report document. • Perform statistical analyses from convenient dialogs in the menu system. • Run analysis functions one at a time at the command line or in batches using the Script window. • Create your own functions. • Completely customize your user interface. 2 Installation INSTALLATION To install the software: 1. Insert the S-PLUS CD into your CD-ROM drive. 2. If your operating system supports AutoPlay, installation will proceed automatically. If it does not, run setup.exe in the root directory of the CD-ROM. 3. Follow the on-screen Setup instructions; default settings are recommended. It is a good idea to turn off other applications (in particular, virus checkers) while installing S-PLUS because of known problems with the installation software InstallShield.

This article is aimed at creating a summary of selected commercial and freeware software, main task of which is to work with data, their processing and visualization. The article includes an explanation of the concept of visualization, defining basic types of software, description of programs, their main utilization possibilities and basic functions and options. Great attention is devoted especially to the open-source application QtiPlot and its detailed description. Keywords: QtiPlot; graphs; visualization; open-source program 1. INTRODUCTION At present more and more different programs for data processing and visualization have been used. These programs may be from the base aspect commercial and freely available. The main difference is in the price and in offer functions of the program. Data visualization deals with digital processing and presentation of the abstract information that may be obtained by measurement, analysis or by statistical methods. The visual appearance of the processed information is for humans more natural and easier to understand than the numerical expression while a man bring closer to the problems of themes, helps to detect and understand the relationships between data and their properties In the past visualization was an instrument which was used especially almost exclusively in the academic environment. Development of information technology has caused, that the visualization became interested also people from other areas of public life. [1] For this reason, new programs for processing and visualization with ever better offer features and graphics have still arisen and developed.
