Purpose
ZVView is a multi-platform software package that has been designed so that evaluators of nuclear reaction data can perform efficient interactive visual analyses of cross section data retrieved from the EXFOR and ENDF libraries. The main function of ZVView is to plot these data for inter comparison, using a variety of options to study graphical, numerical and bibliographic information along with the possibility of analysing the results of the user's evaluations. Since 2010, ZVView was extended to plot 2-dimentional arrays Z(X,Y) with the main purpose to display correlation matrices.

Functions
ZVView allows user to change parameters of the plot, such as: type of data view (curve, histogram, map, 3D, animation, symbols of points, colors, error bars), logarithmic and linear scales, zoom, split plot to sub-windows, smoothing by least-squares method, choice of data and authors to be plotted, and scans of their points, change language on the fly, etc. (see [User's Guide]).

Platforms and Graphic Devices
The program is mainteined on three most popular platforms: MS-Windows, Linux, Mac-OSX (with X11). There is also non-interaction version of ZVView using memory as graphic device instead of window on user's screen - usualy it is used to produce GIF/PS/EPS files on Web-server or as part of another software package.

Output formats
Data together with currect plotting parameters can be saved in ZVD format files - it is container format, native input/output format of ZVView. Pictures can be saved as PS/EPS (PostScript: hight quality vector graphics for LaTeX and CorelDraw), EMF (Windows Meta File for MS-Word), PCX and GIF files (static and animated) for many forms of publishing, including Web. See screen-shots: [1] [2] [3] [4] [5] [more...].

Web-ZVView
User sends own data to Web-ZVView for interactive plotting via Web browser (ZVView works on server side).

Data for testing:
[al27a.zvd] Al-27(n,a) - cross section
[lsttab2.zvd] Nb-93(n,el) - angular distribution
[Ir-193n2n.zvd] Ir-193(n,2n) - correlation matrix
[a2.txt] [a3.txt] [a4.txt] - text files with data in columns: to be used with control files, like [a2.tit] [a3.tit] if necessary

Usage in other packages
As well as stand-alone usage, ZVView is called from other software packages, such as Empire, Endver/GUI, EXFOR-CINDA-CD in interactive mode, from the EXFOR-ENDF Web-retrieval system in non-interactive mode, and also as Web-Browser Helper-Application in several products organized as Html pages with interactive graphics, ENDF-covariances and others.

Background
The ZVView package is based on the universal graphics library DINAMO©, which was written in C-language in 1993-1998 by V. Zerkin at Kiev*. The library was designed to be used on a wide range of computer platforms as universal software tools for various applications in nuclear research. ZVView is one such application developed by the author that can be used for specialized nuclear data analysis. ZVView was developed through 1996 (while the author was working in the Institute for Nuclear Research, Kiev, Ukraine) and has continued to evolve at the IAEA (International Atomic Energy Agency).
