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(X11), Mac-OSX(X11).
There is also non-interaction version of ZVView
using internal memory as graphic device -
usualy it is used to produce GIF/PS/EPS files on Web-server
or by specialized off-line scripts generating, for example, HTML+GIF files.
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, producing PDF, etc.),
EMF (Windows Meta File for MS-Word),
PCX and GIF files (static and animated) for many forms of publishing,
including Web.

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).
